Great place, extremely clean, rules are really clear and easy to follow, I always felt like in home. Lulu and her family are great hosts, they are always trying to keep in touch with you and be sure everything is going ok.
Definetely a great place to stay in San Francisco, great location in a beatiful neighborhood, 15 minutes away from downtown in public transport.
Totally worth it, would stay again with them if I come back.
