I enjoyed my stay at Gail's room very much. It was indeed small, but cozy - I didn't need a lot of room. My girlfriend was also comfortable there, and the neighborhood was quiet and away from the noisiest parts of Ocean Beach. Good ventilation with the fan and half door open, and not very much noise at night (you'll hear aircraft from the airport overhead, nothing too bad though). The place is on a hilltop though, so be prepared for an uphill trek when coming back from the OB seashore area.
Was able to have a quick chat with Gail one of the days. She was very considerate of our privacy and kept to herself unless I contacted her about something specific via the Airbnb message system. An excellent host if I may say, and I'd not hesitate staying at her location again!
