My stay at Daisuke's apartment was really nice. The apartment is clean and well-equipped. Furthermore, the location is very good, a 15 min. walk from Kamata station, from where it is possible to take a direct train to many places (Ueno, Ikebukuro, Tokyo, Yokohama, Saitama!). Near Kamata station it is basically a downtown with many restaurants and shops. I would definitely go back to Daisuke's apartment if I visit Tokyo again in the future.
