Kate's apartment was wonderful: comfortable, clean, well-equipped. Furnitures were all new. Kate and Joey were friendly and lovely, ready to answer to all our requests, but even very respectful of our peace. The quarter was residential, but near to city center (a few bus stops or a very cheap Uber ride). Also airport was very near, as well as the Balboa Park, one of the main city attraction, that should be reached by a 20-minute walk. Neighborhood was calm, safe, and amazing: there were shops very near the apartment, restaurants, pubs, cafes. We had breakfast outside the first two days and after we chose to stay in the apartment.
Definitely, one of my best experiences with airbnb and similar. We are very thankful to Kate and Joey for their hospitality, we strongly suggest their apartment for everyone wants to stay in San Diego.
