We stayed at the casita for two nights and loved every minute of it. The bedroom and bathroom seemed new and renovated (and very clean), and the living room and kitchen area were are also a great feature. We did have a rental car to get around (to the Zoo and to the beaches), as San Diego is a drivable city and much calmer than LA.
Susan was so welcoming and accommodating, and left us with a binder of guides and restaurant recommendations.
If we ever stay in San Diego again, we will definitely try to stay at the casita@
