I had just arrived in San Diego and needed a space to put my moving boxes since I was going to be staying at an Airbnb for a couple of weeks. I decided to use this location since it was nearby and rented a space online. I paid $95.84 total. When I arrived there, I realized the space was inconvenient since I would need to climb a ladder to put the boxes up top. I immediately went to the front desk and requested to switch lockers. The gentleman was nice and did it for me. I was charged again $116 and was told I got the “transfer fee” of $10.00 waived. I didn’t realize at the time that I was paying double for simply switching lockers, and mind you, I hadn’t even loaded anything into the first one. I stayed with the second locker for a couple of weeks (less than a month) and asked if I could receive a credit for staying less than a month. He said no due to company policy, which I understand. However, when I asked for my refund from the first locker, he told me he needed to speak with his supervisor. He later called, saying that they couldn’t refund the first locker that I DID NOT EVEN USE. This is completely unfair to consumers who have no ability to fight back against a charge that shouldn’t have continued since it was never used. I’ll never rent a locker here again. BEWARE
Response from Extra Space Storage (6/9/2026)

My price was going to go WAY UP, but I talked to a kind gentleman there and he was able to reduce my cost after me having moved in just months prior.

Avoid this location if you care about your money or your safety. They just doubled my monthly base rent overnight from $86 to $172 with absolutely ZERO notice or warning. When I called the local manager to complain about paying a premium price for a facility that is filthy, full of bugs, overflowing with trash, and constantly dealing with drug users and heavy police presence, I was told that the unsafe conditions of the property "were not relevant" to my price increase. It is completely unacceptable to double a loyal tenant's rent while letting the actual facility turn into a hazardous environment. Management refuses to take accountability and blames the customers instead. I will be taking this up with corporate and looking for a competitor that actually maintains their property.
