I stayed at this hotel for one full week. Everything about the hotel was perfect. Amazing view from the room, fabulous gym for workouts, extremely courteous staff (despite the language barrier), amazingly prompt service, the works basically. The rooms are well spaced and comfortable. The sleep quality is just amazing. The location is also fabulous. Our business was in the Midtown building, so that was convenient as well.
In the evening, Roppongi is a very short walk away and is extremely lively to help you strum yourself out of a busy office day.
