HOTEL MYSTAYS Iidabashi (Old name: Flexstay Inn Iidabashi)
About an 8-minute walk from Iidabashi Station, with kitchens and multi-bed rooms; a good fit for self-catering longer stays, but check breakfast, cleaning, and upper-floor stairs first.

Choose by living needs, not just a Shinjuku Ward address
- About 8 minutes from Iidabashi Station’s East Exit or B1 Exit — not beside Shinjuku Station.
- Some rooms have kitchens; multi-bed rooms need an actual bed-count check.
- Longer-stay cleaning and some upper-floor stairs need checking; there is also a 5 November equipment-inspection notice.
I would consider this one for Iidabashi, Kagurazaka, and Tokyo Dome trips. Its appeal is more lived-in rooms and multi-person options, so a trip need not mean eating out every day.
By contrast, cleaning, breakfast, and luggage routes need active planning. Asking every condition in full matters more than looking at room photos alone.
In Iidabashi in Shinjuku Ward, no need to route back via Shinjuku Station
The address of HOTEL MYSTAYS Iidabashi is 3-26 Shinkogawa-cho, Shinjuku Ward — administratively in Shinjuku Ward, but its everyday area is Iidabashi, not Kabukicho or beside JR Shinjuku Station. If you are mainly heading to Tokyo Dome or Kagurazaka, or want to use Iidabashi’s many lines, this location means more than the words “Shinjuku Ward” alone.
The official listing gives an 8-minute walk from JR Sobu Line Iidabashi Station’s East Exit, and Tokyo Metro and Toei Oedo Line Iidabashi Station’s B1 Exit is also about 8 minutes. Guests often say roughly 6 to 10 minutes, and some mention slopes; I would start from the official 8 minutes and add time for luggage and finding the way. Elevator exits and a fully step-free route are not yet confirmed — ask the hotel in advance if you need one.

For families and friends staying together, choose beds first, then the kitchen
Formerly Flexstay Inn Iidabashi, it was renamed HOTEL MYSTAYS Iidabashi on 21 September 2024. Remember the time gap when checking older photos; the current gallery already shows different layouts such as sofas, multi-bed rooms, and bunk beds, so do not treat photos under the old name as a guarantee of the same room.
Room types that can be checked include the 20 sqm Comfort Double with kitchen and the 39 sqm 4 Bed Bunk multi-person room; the latter plan can sleep up to 7 people, but “sleeps 7” does not mean seven separate regular beds. For three people, multi-person groups, or children travelling together, I would confirm the actual allocation of main beds, extra beds, sofa beds, and bunk beds item by item, and use the room order’s occupancy limit as the standard.
| Stay needs | Room conditions I would confirm | Re-check before booking |
|---|---|---|
| Couple wanting simple cooking | Comfort Double with kitchen, 20 sqm | Bed width, hob, and tableware list |
| Friends or family, multi-person | 4 Bed Bunk, 39 sqm | Bunk beds, extra-bed allocation, and occupancy limit |
| Three people sleeping separately | A room type explicitly listing three beds | Do not judge only by “sleeps three” |
| Need an easier-to-reach room | Ask the hotel first about floor and stairs | Some platforms note upper-floor kitchen rooms require climbing stairs |

Kitchens are a feature of some room types; guest photos show a sink, hob, and microwave, but not every room in the hotel has one. If you really want to cook breakfast yourself, I would first check pots, bowls and plates, fridge, and cleaning supplies, rather than shopping first and only then finding a tool missing. If you do not plan to cook, you can put the budget toward beds and activity space instead.

Bathroom photos show different unit-bathroom layouts; the spatial relationship among bathtub, washbasin, and toilet depends on the actual room type. The view outside is mainly city buildings and a residential area; here I would value everyday convenience and indoor use, and would not book for the view.

Laundry and everyday facilities are practical — check the stair conditions first
The lobby has a reception counter and sofa area; officially 68 rooms, 15:00 check-in, 11:00 check-out. Photos show shared laundry facilities, which help a lot on longer stays; that does not mean every guest room has a washing machine — check fees, detergent, and available hours with the counter. Washing clothes before heading out also means first checking whether it eats into the rest time you wanted.

Some booking platforms specifically note that the Comfort Twin with kitchen and Deluxe Twin with kitchen are on the 7th floor, reached by stairs from the 6th floor. This matters a lot for heavy luggage and guests with limited mobility; I would ask the hotel directly before booking about my own room type, floor, and full route in — and not assume the whole route is flat just because the building has an elevator.
Separately, the official notice lists a building-wide power and water outage on 5 November 2026 for electrical equipment inspection. If you stay around that date, first confirm the actual affected hours and elevator and water arrangements; if you had planned to work or rest in the room around midday, it is best to plan an alternative activity first.
Plan breakfast around self-catering; kitchen rooms offer more flexibility
The official page I checked currently shows no confirmable in-hotel breakfast menu, hours, or prices, so I would not book this hotel as one with a full self-service breakfast. The safer plan is to buy simple food the night before, or walk toward Iidabashi Station for breakfast in the morning; if your plan lists meals separately, follow the order and the hotel’s confirmation for the contents.
Several guests mention a supermarket across the road being convenient for shopping, which is especially useful for rooms with kitchens. I would buy portions that can be finished that evening or handled simply the next day, checking the room fridge and cooking equipment before shopping. Without a kitchen, convenience meals and eating breakfast out can still keep mornings simple.
With no actual breakfast photos, do not substitute photos of other restaurants. This hotel’s dining value is more like a living arrangement: what you want to eat and when you go out can be decided yourself; the cost is leaving a little time for buying, heating, and tidying up.
For longer stays, the key question is how cleaning is arranged
These ten original guest reviews from 2026 repeatedly mention room space, a nearby supermarket, and the convenience of kitchen rooms, and repeatedly remind readers there is no daily room cleaning. Some guests say towels and sleepwear are exchanged at the counter, and that bathrooms can accumulate grime on longer stays. My approach would be to ask on arrival whether cleaning costs extra, how to book it, where rubbish goes, and the towel-exchange rules.
Do not read “no daily cleaning” as accepting a room that is not clean on arrival. Some individual reviews in this set also report bedding or hair issues; if you actually encounter them, ask the counter at once to deal with it or help change rooms. These are individual negative experiences and cannot be generalised to every room, but for longer stays they are a reminder: first confirm the service method, then judge whether it meets your own standard.
For a short stay of one or two nights, laundry and the kitchen may not both be used, and multi-bed options and nearby activities may matter more; for four nights or more, I would count cleaning, laundry, and shopping together. Anyone who wants a full tidy-up every day on return should first confirm whether the corresponding service can be purchased, rather than comparing room size alone.
Tokyo Dome after-events and Kagurazaka dining can run at different rhythms
Some guests chose this hotel for a Tokyo Dome event and liked walking back after it ends. The official transport page lists about 15 minutes on foot from Suidobashi Station to the hotel, but event exits, crowds, and the actual venue location all add time; I would save the return route in advance and allow a stretch of time to walk slowly, rather than rushing a last-train plan on ordinary-day minute counts.
Another day can be left for dining and strolling around Kagurazaka, then returning to the room to rest. Iidabashi has JR and several subway lines, so heading to Shinjuku, Akihabara, and other directions can be chosen by that day’s destination, with no need to run to Shinjuku Station first. This way of staying is more like setting up a living base in Tokyo, suited to people willing to walk a little further in exchange for indoor space and self-catering flexibility.
Pros and trade-offs: space and a lived-in feel, matched with self-catering ability
| Aspect | Pros | Trade-offs to accept |
|---|---|---|
| Location | Iidabashi’s many lines are usable; good for Dome and Kagurazaka trips | Not beside Shinjuku Station; about 8 minutes from station to hotel |
| Room type | Three-bed, kitchen, and bunk-bed options available | Bed allocation and occupancy limits need checking one by one |
| Cooking | Some room types allow simple self-cooking; shopping is convenient | Not every room has a kitchen; equipment must be confirmed first |
| Longer stays | Shared laundry and a lived-in arrangement offer flexibility | Adjust expectations of no full daily cleaning |
| Routes | Lobby has rest and reception space | Some upper-floor room types have stair notes; ask the hotel first |
| Breakfast | Can be arranged at your own pace | No confirmed in-hotel breakfast; plan on a self-catering basis first |
Want multi-person stays and living flexibility? Ask every condition in full first
HOTEL MYSTAYS Iidabashi suits people willing to arrange their own breakfast, cleaning rhythm, and daily shopping, while looking for multi-person rooms in the Iidabashi area. I would first decide bed and kitchen needs, then confirm floor stairs and cleaning services, and only then look at price. When all these conditions fit, it will be a practical Tokyo base; if what you care about most is a full daily clean or arriving right at a station exit, first weigh these trade-offs.
