JR Kamata Station west-exit neighborhood | 27–30 m² apartments under room numbers 403, 501, and 801 — compare access, beds, and check-in rules first

How would I choose this stay?
- 27–30 m² room types with a clear match between room number, bed count, and occupancy
- All three room numbers are mainly self check-in, with check-in after 16:00 and check-out before 11:00. If someone needs to sleep in, this check-out time is slightly more forgiving than at apartments with a 10:00 check-out; but how to obtain the key still needs to be read in advance, unlike a hotel with a 24-hour front desk.
- Different room numbers come with a double bed, two double beds, or a sofa bed — do not mix them up
The most valuable information about Xe Building is the room number itself: Room 501 is 30 m² with two double beds; Room 801 is 27 m² with one double bed; Room 403 is 30 m² with one double bed plus a sofa bed. These three rooms are in the same building, yet they cannot be treated as the same bed configuration. I would first check whether fellow travelers need separate beds, then compare room numbers.

Location and access: how would I get there, and how would I plan Haneda and central Tokyo trips?
The address is Xe Building, 7-chome 26-8 Nishikamata, Ota Ward. This location’s main living area is the neighborhood around the west exit of JR Kamata Station, which is not the same exit as Keikyu Kamata Station; for Haneda Airport trips, first decide whether to take Keikyu or another route to Kamata, then pinpoint the building entrance.
Nishikamata 7-chome has a mixed neighborhood feel of eateries, shops, and residences. Taking the Keihin-Tohoku Line from JR Kamata Station and taking the Airport Line from Keikyu Kamata Station are two different things; which station you leave from each day decides whether you need to cross central Kamata. I would pick the station-entry route based on that day’s trains first, then handle the final walk to the building.
This area suits buying bento and daily necessities and then returning to the room to sort luggage, freer than staying inside the airport and having to ride into the city to shop. The apartments are managed by room number, and no matter how many shops are nearby, they cannot replace the check-in instructions; groups arriving late need to send the room number and address to every fellow traveler.
I would save the property address in navigation first, and when riding trains keep the Japanese station names as well, so as not to mistake different Ota Ward station exits for the same one. If you drag luggage, change trains, and rush to airport check-in on the same day, you cannot estimate the whole journey from station-to-station ride time alone; the walk from the room door to the station, the walk to the correct platform, and airline check-in each need their own time allowance. The location here is “Xe, 501, 7-chōme-26-8 Nishikamata, Ota Ward, Tokyo, Japan”.
Room types and beds compared: check the room number first, then decide which room to book
I would not compare only the cheapest room type at the same property. What really shapes the experience here is each room number’s bed count, floor area, how many people share the living space, and the balance between sleeping areas and luggage space. When choosing a room, first confirm the actual party size, then compare whether people can sleep in separate beds and how much room there is to move around indoors; price and cancellation terms come last.
| Room type / room number | Floor area | Beds | Known capacity |
|---|---|---|---|
| Room 501 | 30m² | 2 double beds | Up to 4 adults |
| Room 801 | 27m² | 1 double bed | Up to 2 adults |
| Room 403 | 30m² | 1 sofa bed, 1 double bed | Up to 3 adults |
Room 501 | Beds and luggage layout
Room 501 is listed at 30 m², with a bed configuration of 2 double beds. The listing shows up to 4 adults can be accommodated, but headcount and whether each person has a separate bed are two different things. The size sits between a small business room and a large apartment, and how spacious it actually feels depends on how the beds, desk, and living area are arranged. The room is listed as non-smoking, a condition people sensitive to cigarette smoke must verify.

Room 801 | Beds and luggage layout
Room 801 is listed at 27 m², with a bed configuration of 1 double bed. The listing shows up to 2 adults can be accommodated, but headcount and whether each person has a separate bed are two different things. The size sits between a small business room and a large apartment, and how spacious it actually feels depends on how the beds, desk, and living area are arranged. The room is listed as non-smoking, a condition people sensitive to cigarette smoke must verify.
Room 403 | Beds and luggage layout
Room 403 is listed at 30 m², with a bed configuration of 1 sofa bed and 1 double bed. The listing shows up to 3 adults can be accommodated, but headcount and whether each person has a separate bed are two different things. The size sits between a small business room and a large apartment, and how spacious it actually feels depends on how the beds, desk, and living area are arranged. The room is listed as non-smoking, a condition people sensitive to cigarette smoke must verify.
The “capacity” above is how the booking listing assigns headcount; it does not mean there are the same number of separate beds. If traveling with friends rather than a partner, I would first check whether everyone can sleep comfortably on their own; families with children should note that free stays for children often come with a “no extra bed” condition, so free does not automatically mean an extra child’s bed is provided.
Only after deciding on beds would I compare whether luggage can be opened, whether a work desk is needed, and how private and shared space is divided over several nights. With 27–30 m² apartments like Xe Building, Nishikamata, with room numbers 403, 501, and 801, room-type names easily create a false impression; the real way to avoid booking the wrong room is to put room number, floor area, bed count, and fellow travelers’ needs in a single table.
Check-in style, living facilities, and what staying here feels like
Room 501 having two double beds does not mean that, beyond the beds, its 30 m² leaves a lot of room to move; Room 403 counts a sofa bed as one of its beds, serving as a living room by day and a sleeping space by night, so how it is used changes. Room 801 has only one double bed and suits couples or solo travelers relatively better. The photos let you identify the actual interior layouts of 501 and 403.
I would arrange check-in conditions around the room type actually booked and the property’s policy, rather than mixing up photos of different room numbers. This property’s check-in rules are especially worth remembering: the relevant times and methods are listed in the booking information and should be confirmed before departure. With a late flight, staggered arrivals, or onward connections, the sooner the door-opening method is sorted out, the less likely the trip is disrupted on arrival.
This property does not serve breakfast, so I would plan the next day’s meals together with departure transport the night before; when traveling with several people, preparing early beats splitting up with luggage in the morning to hunt for a restaurant.
How to plan morning departures and check-out times
It is confirmed that this property does not serve breakfast. In the morning I would first check whether the day involves catching a flight, heading into central Tokyo, or checking out to move on, then decide whether to take breakfast away or use nearby dining options; traveling with family, I would at least allow time from the room door to the station.
One night vs. a longer stay: the criteria are actually different
Just one night: how to arrange departure and check-in?
If just two people are staying one night, I would usually compare Room 801’s single double bed first, since there is no need to pick 501 only for its “up to four guests” capacity. When staying with friends who each need a bed, 501’s two-bed arrangement may suit better; with a third fellow traveler, first confirm whether 403’s sofa bed is acceptable.
If the flight arrives late, I would sort out the day’s final leg of transport, phone roaming, and battery level in advance — all the more so at a self check-in property. A one-night stay does not require using every facility; what matters is getting into the room smoothly, sleeping well, and leaving by your own check-out time.
Three nights or more: how to balance living space and daily routines?
For a stay of three to five nights, the independent space an apartment offers is more flexible than a small dormitory, but none of the three room types has an endlessly large living room. When working, changing, and dining over a long period, the floor space taken up by 501’s double-bed arrangement becomes more noticeable, so I would compare beds and activity space separately.
For a longer stay I would think about bedding arrangements, daily round-trip transport, and laundry and storage together: if you pass through the same station entrance every day, familiarity with that entrance may grow more valuable the longer you stay; conversely, a room that is too small or shared areas you must compete for with fellow travelers will also become more noticeable over time. Do not decide the whole trip on how convenient the first night merely looks.
Pros and cons I would put into a booking comparison
All three room numbers are mainly self check-in, with check-in after 16:00 and check-out before 11:00. If someone needs to sleep in, this check-out time is slightly more forgiving than at apartments with a 10:00 check-out; but how to obtain the key still needs to be read in advance, unlike a hotel with a 24-hour front desk.
Pros
- 27–30 m² room types with a clear match between room number, bed count, and occupancy
- Close to the Kamata west-exit living area, convenient for daily dining and JR trips
- Check-out before 11:00, slightly more flexible than apartments with a 10:00 check-out
Trade-offs to accept
- Different room numbers come with a double bed, two double beds, or a sofa bed — do not mix them up
- Self check-in requires obtaining key information in advance; not suited to people who need immediate on-site reception
- Rooms 403 and 501 sleep several people but are still only about 30 m², so large luggage may feel cramped
These pros and cons are not labels of good or bad for the property; they let each traveler judge by their itinerary. If my priority this time is the JR Kamata Station west-exit living area and nearby routes, I would rank access higher; if there are many fellow travelers and meals or work inside the room matter, I would confirm bed types and living space before looking at price.
Conclusion: who would I recommend this to for this Tokyo trip?
Xe Building suits people who value Kamata’s everyday amenities and want to stay in a self-service apartment. I would not judge by the lowest price; instead I would first list the party size, whether a double bed or a sofa bed is involved, and how much space must be left for luggage, before deciding among 403, 501, and 801.
My booking order is: first confirm the actual hotel address and transport stations, then identify the room number, floor area, and beds from the room-type name, next check check-in times and whether self-service key pickup is needed, and finally compare total prices. Choosing Xe Building, Nishikamata this way fits the conditions actually needed on the trip better than looking only at star ratings or the lowest nightly price.
