Great space for large groups while providing ample privacy for all individuals. Not good for groups with old or young individuals as there are multiple sets of stairs. Even though there is a bedroom and bathroom on the ground level, the toilets are on the second and third levels, so there is no getting around having to climb stairs just to go about one's daily business. For a group of 7 able-bodied adults, however, this was perfectly fine and we had a great stay in Tokyo.
