We stayed at Shelagh's house for 3 nights, and we were 5 adults (of which 2 couples). The house is very nice, cosy and fully furnished. We felt like at home. It was very clean. The second double bed was a convertible couch, but quite comfortable and we could close doors to have a separate room. The location is good, nice neighbourhood, not too far from restaurants, Dolores park, public transportation. We also used uber to go to the centre which was cheap and convenient as well. Communication with Shelagh was very good. She is very nice and welcoming. I highly recommend Shelagh's place for a few days stay in San Francisco.
