A nice place. Close to the Tokyo Metro Station and 10 minute walk from the Skytree. Residential neighborhood, but has all conveniences you need within a 5 minute walk or so. The building is brand new, finished in June. Daigo and his family live on the top floor of the apartment building and rent out the apartments below - airbnb. So if you have any problems, they are literally in the same building. Very good hosts and will help you with anything.
The apartment itself is very nice and new. Washing machine for clothes, microwave, free WiFi, shampoo etc. all there. Good for family with a few kids. 5 of us and we were ok.
Recommend this place if you wanna stay in the Sumida-ku area. Easy access to other parts of Tokyo.
