Stayed at Yuko's house for 2 nights. It is extremely big and clean. If you stayed there once, you will never consider staying in any other Tokyo hotel.
The room has fully functioned kitchen with dish washers, dishes and appliances for you to cook. The BedRoom is spacious and facing a private garden where in the morning Sunshine will come into the room. Parking lot is also provided in front of the house, makes it really like a home.
The location is perfect as Yuko mentioned, 2-3 mins from the Metro station and some good supermarkets, restaurant and convenient shops. We tried the Noodle house(Ramen) and the bread shop that Yoko recommended, it is fantastic.
Yuko treats us nicely and is helpful to answer our questions and requests. She is able to speak good English.
Overall it is a good place to recommend in Tokyo. I hope I can stay longer next time in this place.
