Namio's house is great. Very close to the Tokyo subway so easy to access, yet away from the masses of crowds around the bigger stations so very quiet and peaceful area.
Namio provides detailed information about places to visit and eat in the area as well as excellent access directions.
The apartment is clean and modern and has everything you need with loads of storage space.
Namio always responded to inquiries quickly and was available if needed during our stay.
I would highly recommend Namio's house for any Tokyo trip as a couple!
