We enjoyed our stay at Joan's place.
It was nicely decorated and themed like a beach house and was very clean.
Communication was minimal because there was a guest book that had all the information and that was convenient. The place had almost everything we needed (including a blender to make smoothies, and board games for the kids to play). The only thing that was missing was bedding for the sofa in the living room. There were only sleeping bags and pillows. We ended up using a flat sheet and blanket from the other beds and made it work, so it was definitely not a deal breaker.
Location was nice, though the neighborhood didn't offer much for families with little kids (no close playground or kids attractions) and the streets were very lively at night, because of all the restaurants and bars, but that was less for us.
There is a shopping area that is pretty close with a CVS, Trader Joe's and more, that was very convenient as well.
It looked like the beach is not too far, but we didn't end up getting there.
Overall it is a great, cousy hideaway for a taste of San Diego.
