We enjoyed our stay at Shannon's place - definitely one of the cleanest, nicest Airbnb homes we've stayed at so far. The sound system, heated bathroom floors, and workout space were some of the awesome extras that made our stay comfortable.
Shannon was also a very thoughtful and responsive host. She gave our 2-year old twins nice baskets to celebrate Easter. And she provided plenty of interesting books and toys to keep our kids occupied.
Would strongly consider booking this place again, if we were visiting SF.
