Sei san was responsive to messages, and very helpful since booking her apartment. The apartment is great overall, but certain appliances could not be used at the same time, which was quite a challenge for us as the weather was freezing cold. We had to take turns to use the water heater and hair dryer. Water heater couldn’t stay hot throughout also. Besides that, everything else was great. Sei san provided towels, toothbrushes, cups, etc. There were two charging ports at each side of the beds, which was convenient for us.
However if you’re travelling with heavy luggages, please reconsider as there are no stairs leading up to the apartment.
