Watch-outs
Things to know before booking
Check these conditions before you pay, especially when a child will share a bed or use hotel facilities.
Every stay requires at least two nights
The property requires at least two nights. It suits families who will use the kitchen, laundry and extra living space.
The booking request is not instant confirmation
Submit the request, wait for the property to confirm availability, then complete its payment process. Do not treat the first screen as a secured reservation.
Published child wording is inconsistent at age 6
The property says both 'under 6' and '0–6' across current pages, while children aged 7 and over are treated as adults. Ask how a 6-year-old is counted before booking.
No breakfast and no daily full cleaning
Towels and trash are handled daily, but beds are not remade and the apartment is not fully cleaned every day. Plan to self-cater or use nearby restaurants.
After-hours arrival must be arranged
The staffed check-in window ends at 18:00. Notify the property in advance to use self check-in after that time, and keep noise down after 22:00.
Child policy
What changes with age
Lodging, bedding and breakfast do not always use the same age boundary. Check the row that matches the child's age at travel.
AgeSleepBeddingMealsBooking action
Age 0–2 years
Sleep The property's family-count rule can allow young children to share, but the exact wording differs between official pages.
Bedding A mini cot, baby futon and waterproof sheet can be requested at least 3 days ahead; the mini cot is not available in 30 m² rooms.
Meals No meals are served. Use the kitchen for bottles, baby food and breakfast.
Booking action
List the child and age, ask how they count, and reserve essential baby items at least 3 days before arrival.
Age 3–5 years
Sleep The property states that two young children can count as one adult, but bedding is supplied only for the confirmed booking count.
Bedding Baby futon, play mat, potty, step, high chair and other items can be requested, limited to six loan items per group.
Meals No hotel breakfast; child tableware and a full kitchen are provided.
Booking action
Do not assume a free child automatically receives a futon. Confirm both guest count and number of sleeping places in writing.
Age 6 years
Sleep Official pages do not use one consistent boundary: one says children under 6, another says ages 0–6.
Bedding Bedding follows the property's confirmed guest calculation, not the apartment's physical maximum.
Meals No meals are served.
Booking action
Ask the property to confirm in writing how the 6-year-old is counted and how many futons or beds will be prepared.
Age 7–12 years
Sleep Children aged 7 and older are counted at the adult rate and need a prepared sleeping place.
Bedding Include each child in occupancy; the large 3LDK units can prepare up to six futons across two tatami rooms plus twin beds.
Meals No meals are served; self-cater or use the neighborhood.
Booking action
Include every child in the booking request and confirm the bedroom-to-futon assignment before arrival.

- Bathroom access
- Available in the apartment throughout the stay

Getting there
Plan the transfer before arrival
This is a small residential property without a 24-hour front desk, so arrange late arrival in advance.
- Use the property's official access directions for the final walk rather than a similarly named hotel result.
- Staffed check-in is 15:00–18:00. Notify the property in advance for self check-in after 18:00.
- Keep the arrival message and access instructions available offline; English-speaking staff are not guaranteed, though translation devices and multilingual manuals are available.

One sleeping item per group; mini cot unavailable in 30 m² rooms.
High chair or Bumbo seat
Counts toward the maximum of six requested baby items per group.
Potty, step stool and diaper bin
