Annette is a great host, always approachable, and very helpful. The flat itself is very nice, good located, close to the center of SF, Chinatown or Financial district just 20 min walk, but also to Pier 39 it's around 30 min by feet. Also the good infrastructure (restaurants, supermarkets, etc.) nearby or just within 5-10 min walk distance makes the accomodation to be highly recommended.
