Service at this hotel is 10/10. However, I was unable to get any sleep. The hotel provides re-usable, thick, plastic slippers which produces a LOT of noise. Given the walls are thin, you can hear your next door neighbors walking around the room.
Unfortunately I had a lunatic next door who was walking around NON stop from 2am to 5am preventing any sleep for me.
The solution is simple, replace those slippers with thin cloth disposable slippers just like every single hotel in Japan and this will solve the problem. Feedback was shared with hotel staff, let's see if they will listen.
Otherwise I love the location, the lobby is gorgeous and service top notch. If you can't sleep, that nullifies the purpose of a hotel which is to sleep after a long flight into Asia.
