David is the perfect host and I felt welcome from the very first minute. Great welcome and communication throughout the entire stay, he really helped me whenever I had a question or needed advice help. The Guestroom was very clean, good bed, well equipped bathroom. The bus on the next corner takes you to the MUNI at Castro in just a few minutes, so the connections are good, even though the house is in a quiet residential area pretty far up the hill towards twin peaks. Walking up is only for the really healthy! I will certainly come back to "my" new second home in SF.
