We loved our stay at Kei's place! We were welcomed by his wonderful roommate, Sakiko, who made us feel at home. The room itself is incredibly clean, and the beds are very comfortable. It was great to have use of a kitchen/living area in addition to the bedroom. Kei's house is in a very quiet area, but is a short walk to the train station from which you can go directly to the airport and other areas around Tokyo. Very highly recommended!
