We stayed six nights. The location is amazing as it is only 20 minute walking distance from the La Jolla Shores Beach. The main house is great and Kathleen was very nice, provided fruit and juice, and invited us for home-cooked dinner. There were other guests staying in this airbnb too, creating a nice family vibe.
The room itself is located in the former garage and accessible via the gym there. There is another guest room neighboring this room and the walls are quite thin. This was not a problem for us though, as the other guest was very considerate. The bathroom is located right across the gym.
Good spot to go and explore La Jolla and San Diego!
