Dan is a great host. He was always very responsive to our questions, regardless of how goofy our questions were. His manual for the unit, which he sent by email a week before we arrived was fine.
Dan's place was great. The unit is spacious, with great light from skylights in the kitchen and bathroom . The two bedrooms, the living room, dining room and kitchen are all spacious and the furniture is ok. Dan's place is within walking distance of the ocean, GGP, and several neighborhood parks. We also walked - many times - to the two nearby grocery stores: Gus's is great but pricy, and Safeway is Safeway. Contrary to some comments, we did not hear noise from the bottom (studio) unit or from either of our neighbors, and the entire neighborhood was quiet. We would certainly stay there again, if it's available when we are visiting SF.
