This was my first time using AirBnB and I have to say that the experience was really good. We spent 7 days at Maria's cottage which was very clean and tidy. She responded quickly via text and email. The neighborhood was safe and quiet, in a great location, and everything was within walking distance. We had a slight issue with the door lock but Maria quickly addressed it. It felt like a home away from home. I would definitely stay there again the next time I visit San Francisco.
