My group stayed in various rooms afforded (economy twin, standard twin & double, suite) by the hotel and we had no complaints. The rooms were clean and spacious (something that we cannot take it for granted in Japan). In addition, the service was excellent (English speaking, free welcome drink every night, free internet) and had good facilities such as laundromat and vending machine (on every floor) Btw, there's a convenience store right at B2. Another plus point is that the hotel is strategically located, with train stations (Shimbashi and Shiodome) within walking distance. Will return!!
