The location of the apartment is ideal! The beach is LITERALLY a 1/2 block away, and there is access to shopping, a grocery market and rollercoaster park all in walking distance!
However; the space is very economic and they don't do a great job of making you aware of what the conditions would be before you book. The apartment office is 4 blocks away, you are expected to provide your own toilet paper and paper towels after 1 roll and you have to wash your own linens, take out the trash and clean the apartment if you don't pay your cleaning fee up front. There is also no installed air conditioning or heat (plug in fan and space heater only) and the entire space is one room with a open vent bathroom door, so there won't be any privacy. The good news is San Diego weather is pretty mild and you won't be sitting in the apartment most of the hottest hours, but they could've done a better job at explaining exactly what your $200+/night is getting you.
