Great spot for a short stay in San Diego. It is quite small so it's better suited for a single than a couple. That being said, my partner and I were more than happy with it for the two nights we were there (it just wouldn't have worked for a lengthier stay).
Definitely watch your head when getting in and out of the upstairs space - she and I are both less than 6 feet tall and still had difficulty wedging ourselves in and out.
I don't mean for the above to sound too negative, as the space was gorgeous and Chaz is very upfront about everything in his description (we knew it was only 200 sq ft when we booked and that there would be some airplane noise).
As long as these factors don't bother you either, the price and location are both fantastic and the outdoor space was a nice extension to make the space feel a little bigger too (it's also blocked off from the street to give a feeling of some privacy). We would happily stay again if we come back to San Diego for a night or two.
