We wish we could give the location SIX stars! Any tourist visiting San Diego will find almost all the major sites within easy distance. A variety of restaurants are in the immediate vicinity, as well. It is indeed close to the airport, but as long as the doors weren't open, we barely noticed. The house itself is wonderful. The beds are very comfortable and the rooms are spacious. The provided equipment (wifi, washer & dryer, etc.) all worked perfectly, and in short, we simply had no surprise problems in staying there as often happens.
There was only one minor discomfort: the guest house was occupied, and the back area between, which otherwise seems like a lovely place to relax, is quite small. We avoided using it as it looks into the guest house. In particular, the hot tub, which they did use, is right outside the main house's master bedroom and bathroom windows.
Chelsea provides a short handbook with lots of helpful advice for staying in the area, such as restaurant recommendations (several of which we tried and were fantastic), and even parking tips for some of the nearby attractions. There was even a "Happy Birthday" banner hanging when we arrived, as we had mentioned in passing that it was one of our kids' birthdays. This kind of personal touch made us feel welcome, which we think is the best thing a guest can say about a host.
