The place is near to bus stop from Asakusa to Tokyo station. You can catch the bus number 24 or 42 (sorry because i don't remember ^^) instead of catching subway to Asakusa station and walking very far to the place.
The owner is very nice and her house is very comfortable. She have a karaoke restaurant and I regret that I didn't have a chance to get there. Once again thanks so much for your support.
