Great spot that is very well located. It is great for two people, but may be a little tight for more than two (the couch pulls out, but it would make the space really cramped if it was pulled out. So if you have more than two, make sure you really like them. That being said, the spot is so well located that restaurants and bars and the beach (and bay on the other side) are all less than 2 minutes of walking. It is hard to beat this spot. My wife and I came down for a wedding and it was such a good time and so well situated.
The spot is a bit small (that is the nature of the location since most places here are small vacation rentals), but worked very well for two people. The space didn't bother us since most of our time was spent outside (why sit inside when the beach is right there). Everything we needed we there for us and Corinne even left a backup sunscreen for us in case we forgot ours (we didn't need it, but it was a great touch).
Corrine was a great host and we look forward to staying here again anytime we are in San Diego.
