Catherine & Micki were two great hosts, very kind to let us use everything in the house plus their guides and maps of the city; they have a beautiful apt located near a bus stop (if you don't hire a car, San Francisco has a good public transport system). The photos shown in the ad are accurate. The neighborhood is quiet and almost residential, to find bars and restaurants you have to walk some blocks away. Micki is a good cook, and we have the luck to taste one of her creation. I would absolutely recommend this location even if it's not in the heart of Castro.
