Helen and the group were great hosts. Very fast in their communication, efficient responses and a very nice place to stay. A looked after property and a good facility for two couples. SF is only 20 minutes drive, be prepared to pay $5-7 (one way - cash accepted) over the bay bridge. We found some of the house-rules restrictive such as the complex garbage collection and the long quiet hours. Apart from this, we were very happy with our stay and would easily stay again.
