Nate was incredibly prompt in following up on my booking (love the Instant Booking feature). He sent me several great suggestions for things to do in SD, and met me when I arrived with some more tips.
The casita is a converted garage, nicely done, with large bathroom. The bed takes up most of the studio space, so there's no room for a chair. However the little kitchen is sufficient for snacks and has a microwave. The garden view through the french doors and small patio are really nice. Great neighborhood. Although it's a few blocks from the I-5 and train tracks, it's really quiet. And the proximity to airport, downtown, beach and La Jolla are terrific—about 20 minutes to each. I'd stay there again in a heartbeat.
