    Read some helpful reviews of A - 1 Self Storage, 556 West Main Street, El Cajon, CA 92020, shared by real renters with genuine experiences and honest opinions.

    So far so good. Staff on premises on Sunday and there to help within minutes. All staff we encountered are super friendly. Second floor (interior access) storage is cheaper. No light or outlets inside the unit and it can feel too dark, but, I guess, that is to avoid paying for people doing weird stuff inside. Don’t get freaked by a couple of homeless customers, they are harmless. ... Read more

    I rented a 5x 10 unit that was supposed to be FREE for the first month yet I was charged 45 dollars. That's not free. Then I was called and told to come in to " finalize" everything. Then I had to buy a lock. What they didnt say was the storage unit was half way down the yard and NO way to get there except to walk in the heat all the way down . For a person with a bad hip walking all that way is HARD and did Jessica wait for me? Nope she walked 10 paces ahead of me. And then come to find out my storage unit was upstairs and they had no elevator for me to get up there. I can't take the stairs with a degenerate knee disease and a bad hip. Did Jessica offer a different storage unit? NOPE she just walked 10 feet in front of me back to the office and said well maybe you can go to my sister storage in LA MESA. FYI JESSICA don't ASSUME someone can get to another town!!! And get a damn golf cart at least to drive people DOWN to their storage unit!!!!!!! FYI JESSICA DID KNOW ABOUT MY DISABILITY I TOLD HER WHILE WE WERE WALKING TO THE UNIT BECAUSE SHE POINTED OUT THAT I WAS SLOW AND IT WAS A LONG WALK!!!! AND YOU NEVER OFFERED 2 MONTHS FREE!!!! AND YOU HAD A 5X10 GROUND UNIT AND A ACCESS ELEVATOR I WAS NEVER OFFERED!!!!! DISCRIMINATING ... Read more
