This place is in a great location. Less than a 10 minute walk to the beach, restaurants, and bars. It's a bit tight if you have to use the air mattress, but well worth it for the location.
However, if its going to be a bit hotter than normal in SD and you are not tolerant of the heat/humidity, you might want to give it a pass as there is no AC. The fans do a lot to help but if you need AC to sleep soundly, not the place for you. It was pretty humid (coming from DC swampy standards) the first couple days of our stay and the fans did little to negate that. Later in the stay it went to more San Diego weather and it was great.
Will definitely book again, will just keep my eye on the humidity :)
