This place is great. It is located right in Shinjuku, near all the cool nightlife (Golden Gai, Kabukichou, etc). Also is right in the middle of Shin-Okubo, so if you like Korean culture as well, you get the best of both worlds.
Min, the host, is a really great guy. He waited for me even though I checked-in late in the night and welcomed me with drinks, snacks and good humor.
Also, while staying there, I met a swedish guy who was its third or fourth time staying there, which goes to say how nice this place really is.
I would definitely stay here again!
