Amazing flat, great location, very clean and pretty. Great value for money in Tokyo, such nice comfortable shower - a real pleasure after a long hot day of exploring! I stayed in Tokyo for two nights and was able to explore most of the city from the flat - just take the underground anywhere and the flat is right next to an underground stop.
The only negative is check in time. Make sure you are arriving after 4pm or be prepared to pay 1000yen per every hour that you want to check in earlier by. In my opinion charging people to check in early is unnecessary if the flat is already clean, empty and ready to go… and 4pm check in is quite late.
