We went to visit Tijuana and San Diego, but wanted to stay somewhere on the trolley line for convenience. This rental is perfectly situated to get to both the border crossing and all the downtown places we planned to visit (Gaslamp, Civic Theater). Additionally, street parking at the place was super easy, right out front. Plus we were only 11 minutes by car from Imperial Beach (sunsets!) and less than 20 minutes to Del Coronado for a lovely afternoon exploring the hotel and enjoying the beach.
The place itself - very clean. Has everything you're going to need in the kitchen, bathroom, bedroom. We missed nothing.
Note that due to it's super quick access to the trolley line, you can hear the trolley in the apt when the windows are open. However, it does not run 24 hrs, and the bedroom is on the opposite side of the building from the tracks, so we didn't have any issues with this.
Bonus - A little 24 hour taco place is next to the 711. Worth heading over there for late night munchies. Tacos are HUGE!
