What a great place to stay in San Diego!
If we go back, we would choose Efrain's place in a heartbeat.
The apartment is greatly situated just North of Balboa Park which you can walk to. Shops are a short 10 min walk as well. It took us about 20 minutes by car to reach La Jolla, Cabrillo Monument so I would say it is centrally located and perfect as a visit starting point.
The apartment in itself is well organized. We had plenty of space in the living room and we appreciated having the two rooms. The place is bright, well stocked and stylish.
Efrain was really responsive to our message and everything was ready and very clean for our arrival. We highly recommend staying there!
