This was one of my best experiences through AirBnB! Gary's place was very clean and spacious. There were nice touches throughout - like extra toothbrushes in the bathroom if you forgot yours and a list of restaurants/things to do by the door. It was a great location. An easy walk to the Gaslamp Quarter (make sure to check out the Donut Bar and Extraordinary Desserts, both are close by!) and to Balboa Park, and a fairly inexpensive ride to the beaches.
Frank, Gary's manager, was also super quick to respond. We checked in very late at night and had an issue getting into the room, but Frank responded immediately and helped us out despite the hour. Overall, a really great experience and I'd definitely come back if I visit San Diego again!
