The space is quite large with the two double beds, two single beds and sofa bed. We were a group of five people and we were able to stay there quite comfortably. The house was clean, amenities were provided as listed, and location was close to the Shibuya, Shinjuku area where we spent most of our time. However while it is possible for five or six to stay at this location, I think more space is desirable for putting luggage. To make up for this we kept our luggage cases on the spare bed
