Keiko's house was fantastic and met the needs of our group of 7. It is very close to Minowa station. Keiko picked us up from the station when we arrived and went over everything in the house. She has also prepared some snacks for us as well. She lives next door and was very quick to respond to any questions we had. She also took time out of her day to take us to a local festival that was occurring while we were staying. The futons provided were also very comfortable.
There is plenty of places to eat or shop in the area. Asakusa is also only a 15 minute walk away. I would highly recommend this place to anyone staying in Tokyo and would stay again if I am ever in Tokyo.
