Kelly's place is simple, clean, and perfect... as long as you're not visiting San Diego during record high temperature and humidity. We grew up in San Diego and visit every year, so we weren't expecting record high nighttime low temperatures (near 80) and record humidity.
Unfortunately, this made the lack of AC a real issue for us. Of course, we would have never thought to worry about AC in Hillcrest, so that's on us, not Kelly. But it did make for a somewhat miserable stay.
Other than that, the place, was very clean and as advertised. We totally recommend Kelly's place with the caveat that during the "new normal" summers, no AC could be an issue.
