Gary's welcome was warm and informative. Since I was visiting family, I wasn't in the place much, but I enjoyed my hosts' company and advice. Gary is a collector, and the spotlessly clean and comfortably furnished apartment is filled to the brim with an extraordinary array of paintings, photographs, and other art works.
The location is dangerously good - Bi-Rite Creamery and Market, Tartine Bakery, Delfina Pizzeria are all on 18th Street, within a block or two. Do go a few more blocks for Indian, Thai, sushi, wines, etc. Yum. Dolores Park, just across the street, is a wonderful place to hang out. And BART and the bus are very easily accessed.
