The owner is the most impolite Japanese I've ever met. I didn't feel I was welcome at all, the owner doesn't care about his guests, such a disappointing experience. It's not even a hostel, just a cheap place you could stay for a night, nothing else.
There's a man who was sitting on the first floor,talked loudly on the phone and got drunk. For girls, it's kind of dangerous. What if he came to female floor? There's no door and lock for each bed. Well, it seems like you stay in a window for a night. The bed is comfortable though.
Maybe the greatest hostel in San Francisco!!!
