I would perhaps have liked to stay in an hotel in central SF,but prices are just too extrem for normal mortals. Parking charges at a lot of the options we looked at exceeded what I would call a normal room-rate. Danna's house is beautiful, the room was great and Danna did all she could to make us welcome. Berkeley is well outside downtown SF so you will need a car to get around unless of course you are heading for downtown SF when you an use the BART rail system.
Would recomend this location any time.
