I think their service and altitude was not hardly surprising if you consider their price. The most thing I was surprised was, there was a cleaning stuff coming to my room using his keycard before I opened the door. It was quite scared although he just wanted to check if there is a safety box in my room or not. And the manager on the hotel just apologized for that but he didn’t do anything else. If you are in Japan, they must have more service for express their guilt.
Anyway, their room was good and big enough. I checked in early and paid extra fee but it was worth.
It has a nice gym and swimming pool. A bit far from the airport. If you like shopping mall, this hotel is a choice as it's attached to a large shopping mall.
