We stayed at a Superior Queen room on the main building, level 5. It was cozy for 2 adults and 2 kids. They changed the sitting bench to and extra bed. There was no closet or drawers to unpack clothes. There was one little table, about 3 square feet, for everything - tissue box, alarm clock, hot water maker.
The bathroom was small but clean. Everything was made by Toto. The bathroom unit itself was made by Toto and the floor is elevated, so for a regular person, it can feel pretty tight.
It is very convenient to the shopping areas, and the Okachimachi and Ueno Stations.
There's a lot of small restaurants, but because they allpw for smoking, there are no minora allowed.
