I only stayed one night but I really did not like my stay. It was definately the worst hostel I have stayed at in Japan, and being a solo traveller I have stayed in hostels in Hiroshima, Kagoshima, Okinawa, and Ishigaki. The place was hard to find at night and with large luggage, staff was not friendly (worst japanese service I have ever experienced), carpets were stained and dirty, room was cold (they insisted on leaving it at 20degC in the winter) and had no wifi (had to go to lobby on a different floor for wifi which was very inconvenient). The other guests were mostly groups and were very loud. It felt like I was staying in a college dorm. For thr price, you can find a better hostel/guesthouse/capsule hotel somewhere else.
