Andrew and Isabelle are two amazing hosts. The space is really comfortable, we were 6 staying in the apartment and we made it! Andrew and Isabelle even gave us away some pastries. The location is really convenient, there's a grocery store around the block. The grand avenue is two blocks away and it has a lot of restaurants and retails.
Although SSF is a really boring town. Staying in Andrew's and Isabelle's home is one of the best options for SF travelers.
