Yoshio' house is 3minutes from Uguishidani JR station by walk, which is good if you come from Narita airport by Skyliner.
The house is fully equipped, I stay in the 3rd floor, the room is private, with a balcony for smokers, just cannot ask for more because Yoshio had offered everything you need in the house.
Yoshio is a very funny and nice person to talk to, he is willing to help and advice your trip in Tokyo, I enjoyed some much in the house.
