I just needed an inexpensive place to crash during the week while I was in San Francisco, but I ended up having an unforgettable experience. It was my first time in a hostel, so I was nervous about sleeping in a room with so many strangers, but everything was safe and as quiet as FiDi can be. The hosts were cheerful, friendly, and helpful. There were a surprising number of amenities. I met wonderful folks from all walks of life from all over the place. 10/10, will be back again!
