Good place for a short stay in Tokyo, about 10-15 minutes from Shinjuku station, and 7-10 minutes from Higashi-Shinjuku and Okubo stations. Convenience stores are very close by.
I visited in summer, so if you happen to get a bed next to the window the sunlight streaming in in the early morning (6am) can be disruptive to sleep. There is also only one shower room, although I never had to wait to use it during my stay.
The sleeping area is compact but spacious enough to feel like you have your personal space (even if the rest of the beds are occupied). Min and Haru also provide all guests with one small towel a day.
