I loved this hotel, the room is small as you should expect in Tokyo, but well designed it’s comfortable. The hotel is VERY clean, it feels brand new. The mattress is very firm as is common in Asia, I don’t mind it but many western tourists may want something softer, the hotel would be wise to offer memory foam mattress toppers to accommodate western tourists.
Roof top patio was wonderful, having an outdoor smoking area for guests rather than an indoor smoking room is great to keep the hotel from smelling like smoke. I have stayed at dozens of different hotels in Tokyo over the years and this is in my top 5. It was cozy and comfortable, Air conditioning worked great, shower water pressure was amazing, soap provided was high quality, I would definitely stay here again.
