Access to the reception and capsule rooms were via a lift, with no stairs AFAICT. Check in was quick and efficient and I was given instructions about the hotel, my capsule and directions.
I was on the 4th floor, which had about 24 capsules, a laundry room, toilet room and shower room. The latter two were clean throughout the stay and had plenty of cubicles for all the guests. In the shower room, each cubicle had soap, shampoo and conditioner. There were 4 sinks, each with a seat, mirror and hairdryer. Fresh towels and pyjamas were provided everyday.
The capsule was more upmarket, being only a single deck and a personal locker underneath the bed. There was a thick cover, private light, one power outlet, a mini table, a TV and a privacy curtain. The mattress was Asian style and firm, but I found it comfortable.
There was a common area on the reception floor which had loads of manga book, many of which were in English. There was probably enough tables and chairs for 20+ table. I though it was a really nice place to work on my laptop or just relax.
Overall, I had an excellent stay and would happily recommend this place to anyone.
The staff speak enough English to interact with international guests and provide excellent Japanese standard of customer service.
