Hisao's place is great. It is a really nice appartment, stylish and clean. Hisao was really fast to answer, and he allowed me to change the check-in time a few times. Also, he drove me to the station the check-out day at 7am, that was really nice. Too bad I couldn't assist to a kendo class! The location is alright, close to the Ueno Park and the Yamanote Line.
