Read some helpful reviews of Extra Space Storage at 1620 South Interstate 35, shared by real renters with genuine experiences and honest opinions.

They lure you in with a “special price,” but after just three months, the rent jumped up by $45 — and then only two months later, it went up another $35! The prices are ridiculous for such a small unit. To make it worse, there were no rent increase notices, no emails, no text messages — nothing. You will only see the higher charge appear on your bank statement. Totally unprofessional and unfair. ... Read more

First, I have rented from life storage ( acquired by extra space ) for 9 years at 3 locations now. The quality is as best as you can expect from a storage vendor, especially the climate controlled units. I want to take a minute to acknowledge an Extra Space employee in San Marco's, TX. Her name is Hilda; she is a manager overseeing multiple San Marcos Extra Space properties ( I believe). Hilda went above and beyond to help me secure a specific sized unit which allows me to consolidate a.couple storage units and not break the bank. My timing was tight. Hilda put me on a watch list and called me several times to put me at ease to know the One single unit coming available which would meet my needs was mine for the asking once the former leasee moved out end of Aug. I had contacted several properties, competing companies. Hilda is a thoughtful problem solver committed to securing a tenant in the space they need. Hilda called me on Labor Day to tell me the unit I requested was available for move in. I think she deserves double time for working the holiday and taking care of customers. ... Read more

Hilda was awesome! Great experience. Very polite and helpful! Renting a unit was fast and efficient. I rented in a hurry and was fighting traffic to get there before they closed. They agreed to stay a little past closing to help me because the contract was not showing up in my email and I needed a unit that night. Luckily I made just before they closed and didn't need to inconvenience them. ... Read more

Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.
