Very noisy but clean and central.
I had mixed impressions from this hostel. The staff were a bit weird, and the big breakfast hall tends to be immensely noisy. They sometimes have parties and music in the big hall, which is really incredibly loud. My room was a five bed dorm, not very big but you were able to move in there with five people. It had a sink which was full of stuff, and I didn't really know whether that stuff belonged to the other people in the room, or whether nobody took care of throwing it out. There were only common bathrooms on the hall, but at least they were real bathrooms and not co-ed. Most of them were showing signs of long periods of use. Breakfast is free and plenty! The kitchen provides bagels, spreads, cereals and several kinds of drinks. Very sufficient.The Wi-Fi worked fine, but only in the common rooms. Reception in my room was very bad and I kept getting thrown out, so sitting down in the common rooms is really the only thing you can do if you want internet. There are also computer there which you can use to surf for free. The location is perfect, the hostel is right between Chinatown and San Francisco's Italian neighborhood. You can walk down the hill to the financial district in about twenty minutes, or walk up to the Bay and the Pier in half an hour (depends on how good you're at climbing hills). I walked from the hostel via the Exploratium to the Golden Gate Bridge, took half a day or a bit more maybe. Very noisy, even twice as noisy on the weekend. The breakfast is good, the facilities are clean enough to not complain, and it's definitely the cheapest accommodation you can get in the middle of San Francisco.
