Although we never met Billy, John was very welcoming as soon as we arrived and immediately chatted to us like we were old friends. We felt very comfortable in their wonderful, art-filled home and the cowboy themed bedroom was amazing! The neighbourhood seems like a really cool place too and well-located, although we didn't have very long in SF to properly explore it. Staying in interesting places like Billy and John's is what airbnb is all about and we'd highly recommend it to any prospective visitors!
