We had a great stay. Miyuki-san was helpful and friendly, and the home was clean and comfortable.
The location (for those not familiar with the Tokyo area) is fairly convenient for accessing the western part of the city (Shinjuku, Shibuya, etc.) but it's a bit of a trek to get to northern/eastern areas like Akihabara, Asakusa, or Ueno. Just something to be aware of.
If you don't like the idea of staying right in one of the major tourist areas, and/or don't like the daily rates that tend to go with them, this could be a great alternative.
