This RV Park gets 5 stars purely for it's location.  Drive in, park and then walk to all the sights you want to see in San Francisco.  A short 10 minute walk from the RV park is the ferry that will drop you off downtown San Francisco.  We spent a week here and only drove when we wanted the experience driving down Lombard St and driving across the Golden Gate Bridge.  Otherwise we took the ferry and then public transportation to all other points of interest in the San Francisco area.  It truly is nothing more than a parking lot with hookups.
