The house is in a perfect location, close enough to the city (only about 3 minutes walk to the subway and just a few stations to the city centre) but far enough from the city's noises. The size is just nice for two people, with complete housing needs and it's very clean. I enjoyed my stay in Tokyo mainly thanks to Namio's hospitality.
Namio is a really great host, he responds promptly to your needs, very understanding and helpful! He also provides everything you need as a traveller in Tokyo. I couldn't ask for a better host.
