Simon's spacious place is not your ordinary Airbnb. It offers superb views over the Bay Area, has a special (modern) architecture with high ceilings and a great master bedroom with separate shower/bathtub/toilet and Garden access. Really a great place to stay.
When we were there the hostess was Mara, who lives there too and takes care of the place for Simon. She was really great, always friendly, chatty, happy to help and giving her personal tips for our stay in San Francisco. We had a great time staying there and will definitely go back if we are in SF the next time.
