Hotel Petit Bali Garden Shin Okubo – Adult Only
Many facilities are free, but first check the room size and the hours you can actually use them.

For adults who want to spend some time enjoying the hotel itself
- An adults-only couples hotel that does not accept children; a different format from a regular business hotel.
- Basic Value/Pretty rooms are 11㎡ and Villas are 29㎡ — do not mix up the photos.
- The private open-air bath and bedrock bath are reservation-only; free does not mean walk-in.
Shin-Okubo usually brings Korean food and beauty shopping to mind, but Petit Bali Garden puts Balinese-style decor, foot baths, drinks, and private baths together. To me, it is more like a stay where you spend part of the evening enjoying the hotel itself, not just a different place to sleep.
But first you should know that it is an adults-only couples hotel — a Japanese Couples Hotel / Love Hotel — and not suited to family trips with children. If adult friends or a partner can accept that format, then look at whether the room types and shared facilities suit you.
One thing I would stress: lots of free facilities is not the same as a large room. The 11㎡ basic rooms are still compact; if two people bring large suitcases, do not assume every room type is spacious just because the photos show an open-air bathtub and a sofa.
Access: About 3 minutes from Shin-Okubo Station — do not confuse it with JR Shinjuku
The official address is 1-6-7 Hyakunincho, Shinjuku-ku, Tokyo, about a 3-minute walk from JR Shin-Okubo Station and about 5 minutes from the north exit of Seibu-Shinjuku Station. Travelling on the Yamanote Line, Shin-Okubo is an easy gateway to plan around; if you arrive by airport train or a long-distance bus from Shinjuku, you still need to get to the relevant station separately.
I would treat Shin-Okubo and JR Shinjuku as different stations, rather than applying the same exit time whenever a hotel description mentions Shinjuku. The difference matters most when you are carrying large suitcases, have lots of shopping, or are rushing to the airport.
Check the regular exit and the step-free lift route separately. If you need step-free access, look at the JR or Seibu station map first and ask station staff for help, and do not take the five minutes from the north exit as the total time from any platform to your room.
This hotel has no parking of its own, so drivers need to find a nearby parking space. If you want to use a partial parking-fee subsidy, ask about the current conditions first; do not treat the subsidy as making every space free, and do not wait until arrival to look for a space that fits your car’s height.

Rooms: An 11㎡ small room and a 29㎡ Villa are two different ways to travel
The official Value and Pretty room types are 11㎡ with one double bed and a three-piece unit bathroom. They suit one person or a light-packing adult on a short stay; if two people each bring a large suitcase, be ready to unpack in turns. A canopy bed has atmosphere, but it does not make the floor area any bigger.
Moderate rooms are 14㎡ and Superior rooms 19㎡, with other versions that come with a terrace or different audio-visual equipment; Royal rooms are 27㎡ and Villas 29㎡, each with two double beds. When considering an upgrade, I would first look at the actual area, the number of beds, and the bathroom, rather than only the premium-sounding words in the room name.
Villas have a private open-air bath for the room, which is a different facility from the reserved private open-air bath other guests can book. If you want to use a private open-air bath in your own room at any time, choose the room type that clearly includes it; do not book a basic room and then expect the same setup shown in Villa photos.
There are only a few of these larger room types, and even several adult friends travelling together must confirm the permitted number of guests and beds under their plan. That a room can fit several people for a get-together does not mean the same number can stay overnight, and two beds certainly do not make it a family room you can bring children to.

Private baths and bedrock baths: Free, but remember to reserve
This hotel has a reserved private open-air bath and a bedrock bath, officially listed as available 24 hours, in 40-minute slots per group, by reservation at the front desk. Only after finishing one slot can you reserve the next under the rules, so I would first ask what times can be arranged, then decide on dinner and outings.
The open-air bath is officially labelled an artificial hot spring, so do not treat it as a naturally flowing spring. The bedrock bath is another kind of heated-stone relaxation space, and it is not a private sauna in every room. An outdoor pool of water in a photo does not mean there is a swimming pool.
The garden foot-bath area is good for sitting down briefly, and there are other facilities such as reservation-only karaoke. These are very appealing if you are happy to stay in the hotel; if the whole evening is already filled with restaurants and shopping, you may end up with no time to use them.
I would just pick one or two facilities I most want to try. Packing in every free item can be more tiring than going out; if you want to relax, it matters more to leave some unhurried blank time.

Breakfast and snacks: First tell the free drink bar apart from a proper meal
The hotel’s current official services page lists free drinks, bread, snacks, and seasonal desserts, which suit people who want something simple to eat. That is not the same as a large breakfast buffet, and photos of waffles or desserts should not be taken as a full Japanese breakfast.
The hotel’s official page also clearly states that Petit Bali hotels do not offer room service; some general descriptions still mention it. I would go by this hotel’s clearer statement, and if you want a proper breakfast or a specific meal, ask the hotel directly how it is currently arranged rather than assuming the earlier breakfast times shown on a booking platform.
If in the morning you only have coffee and bread, the self-service supplies may suit you well; if you want a full hot meal or already plan to explore Shin-Okubo restaurants, I would eat out. You can bring your own food or use delivery, and the room’s microwave and refrigerator leave room for simple handling.
The drink bar offers both soft drinks and alcohol; adults should still drink at their own pace, and there is no need to try every kind just because it is free. The food and drink items and refill times are as on site.

Nearby: Shin-Okubo shopping and dinner can be planned as one outing
This location suits people who like Shin-Okubo Korean food, coffee, and beauty shopping. I would put dining and shopping in the same afternoon, drop things off back at the hotel after shopping, and then decide whether to use the foot bath, the private bath, or go out for a walk.
To get to Shinjuku, you can also take the Yamanote Line or walk the actual route, without building a big-station transfer into every plan. In the evening, carrying full shopping bags, knowing the way back clearly will feel easier than following the map down the shortest alley.
Some guests describe finding a relatively quiet alley near the lively streets, while others simply like being near the station. I would not therefore guarantee that every room is free of street or neighbouring-room noise; light sleepers can still state a preference in advance and see whether it can be arranged.
Late check-in: First confirm which time slot you actually booked
The official general-stay listing gives check-in from 18:00 Sunday to Thursday and on regular holidays, from 21:00 on Fridays and the day before a holiday, and from 22:00 on Saturdays and mid-holiday days, with check-out times also differing; other platforms or special plans may differ. So I would look at my own booking time rather than treating one time slot on the front page as the same for every booking.
If your flight arrives in Tokyo early, arrange luggage storage and daytime plans first, and do not assume you can enter the room at 3 p.m. Also do not treat a daytime rest plan as an overnight stay; when choosing a plan, check the full period of use first.
For consecutive nights especially, confirm whether you can stay in the same room, whether the room can be left during the day, and how cleaning and luggage are handled. The room’s microwave and amenities are convenient, but they do not replace a clear multi-night arrangement; only after asking will you know whether it works as a Tokyo base for several nights.
When going out, the hotel officially asks you to hand the room key to the front desk; understanding that process first makes evening comings and goings smoother. For consecutive nights in a basic small room, keep up the habit of tidying; as clothes and shopping accumulate, the 11㎡ limit will feel more obvious than on the first night.
Limits I would consider first: Small rooms, and whether facility hours fit your plans
The original reviews mostly praise the amenities, self-service drinks, and service, while some guests directly warn that the rooms are small. Both feelings can be true at once: rich shared facilities do not mean the space for sleeping and sorting luggage is large.
If you expect a traditional large-hotel reception, a fixed afternoon check-in every day, or a family-inn style arrangement, this hotel may not be the best fit. For adult friends or a partner, understanding the couples-hotel format first and then using the shared facilities at your own pace makes it easier to enjoy what is special here.
If you want a non-smoking room, choose carefully: some room types are only partly non-smoking, so do not apply a gallery photo or one guest’s smoke-free room to the whole hotel. People with large suitcases, who are sensitive to smells, or who want to specify facilities should confirm the room name before booking, not just leave a note.
Pros and trade-offs at a glance
| Aspect | Pros | Trade-offs to accept |
|---|---|---|
| Location | Near Shin-Okubo Station, convenient for dining and shopping | JR Shinjuku and airport transport still need separate planning |
| Rooms | Canopy beds and Balinese style have character | Basic rooms are 11㎡, tight for two large suitcases |
| Baths | Free reserved private open-air bath and bedrock bath | 40 minutes per group, reservation-only, not walk-in |
| Food and drink | Free drinks, bread, and snack supplies | Not a large formal breakfast; room service follows this hotel’s own rules |
| Stay format | Adult friends or partners can plan time inside the hotel | Adults-only couples hotel, not for families with children |
| Consecutive nights | In-room microwave and refrigerator are practical | Evening check-in, daytime room use, and cleaning need confirming first |
My pick: For people happy to use the shared facilities and accept a small room
If you are an adult traveller who likes Shin-Okubo’s facilities, can accept the couples-hotel format, and is willing to leave time to reserve a private bath, use the foot bath, or enjoy the self-service supplies, I would put Petit Bali Garden on your comparison list.
I would first choose the area by the amount of luggage, then look at whether what you really want is a private open-air bath for the room or the shared reservation facilities. Once you have the hotel branch, the non-smoking status, and the time slot clear, this hotel’s Balinese style and detailed facilities can more easily become a plus for the stay.
