I found my stay at Julian (Jack) amazing, he is a great host, very kind, interesting and great to have a conversation with. He is pending all the time of anything in the house, which I found clean and cozy. The room is awesome, quiet, big and very comfortable.. a great option to stay in San Francisco.
SF touristic places are only 30 to 40 mins away in public transport, many options and very accesible for a city like SF.
Definitely this is a great option in SF.. very recommended
