First off -- location is perfect. About 8 minutes from the airport/airport rental car garages. 6 minutes to Pacific Beach. About 10-15 minutes to everything else -- La Jolla, Downtown, Gaslamp, Little Italy, the Zoo, etc. Even with some traffic, it only took about 21 minutes to most of those areas.
Second -- it was a very clean unit. Updated too. Felt very safe. Easy to get in and out and locking up.
Third -- Robert does a great job at communicating, asking when you will arrive, shows you the place, check out is painless, everything works
Pro tip: Rent a car. Visiting San Diego is not like an east coast big city where most things are walkable. Especially this unit -- while great location to drive everywhere, not really in an area that has much stuff to do in walking distance (though being able to walk one block to the liquor store/mini market did come in clutch for water bottles, snacks, etc.). This unit is perfect for a rental car since the garage is located in the back alley and is easy to pull in and out of.
