We really enjoyed our stay at Fir's place. It is in a direct flight path so there is quite a bit of plane traffic. One of us was in San Diego for work and was able to walk to the Convention Centre (about 25 minutes) however we didn't walk back in the evenings due to it being quiet and not being sure about safety. We were able to get a short run in Balboa Park in the mornings and one of us who was not traveling for work had a car so could drive to other locations. Fir was excellent with communication from check in and throughout our stay. We initially parked on the street, however we moved our car to the underground parking part way through the week for security. Again, Fir was hugely helpful with facilitating this. Overall a great place for our needs (short visit and not spending a huge amount of time at the apartment during the day).
