The location of the Hostel is close to Tokyo station(train ride 15min) but far away from Shibuya, Shinjuku, Roppongi. Expect at least 30min ride for/ from those places. The hostel is also located in an old neighborhood of Tokyo, with fallen shops and bankrupt facilities everywhere around. Also, a lot of beggars wander over there at night what might be dangerous but the hostel is located 1 block away from a big police office box (KOBAN), what would discourage any type of criminal acts, I believe.
The staff was polite, and showed me the venue, besides the timing for shower etc (AM 7:30-10:00 / PM 17:00-22:00). I had no other further problems as theft, they have also advised me to keep my stuff locked in case I would go somewhere (please note here that I can speak japanese). I had no problems with bed bugs or cleanliness, as reported by other users.
