You get what you pay for; a mostly clean private room doesn't come cheap in the Bay Area. It's a 7-bedroom house so fridge space can be limited, but the other guests I stayed with were all good to talk to so the communal aspect was a plus. People also work different schedules so the house never feels crowded. There is plenty of bus access to downtown Oakland and San Francisco; I found commuting by bus to be more pleasant but more time-consuming than BART. I usually felt safe walking home from the bus stop (even at night), but the nearby commercial streets do not seem safe.
It was good for my purposes (temporary housing for someone who works in San Francisco). Would recommend.
