This is a fairly nice place to stay in SF for a little over $100 a night if you can deal with dorm-style bathrooms. It's one of the very few places to stay outside of the Union Square or Embarcadero area. The value is pretty good, especially for longer stays, and the location is good for commuting to several parts of the city by transit.
My room with 1 bed was nicely furnished. Toilets/showers are shared, but you get a sink. Rooms also have a safe for valuables. Ask for extra blankets; it's cold. Washer is $4, dryer $2.50. Service is good; I was promptly helped back into my room after getting locked out.
On the down side, there's no microwave or kettle in room, the showers are a bit small and damp, and this street can get noisy and rowdy.
It's a good enough value I booked for a second week here.
