I visited the Santee location today, 10/3, and Jayann was the representative who assisted me. She was absolutely fantastic! She was friendly, understanding, and always willing to help. She's honestly one of the reasons why every visit to my storage unit has been such a pleasant experience. To me, that's what great customer service is all about, having someone who genuinely cares about their customers and goes out of their way to help. It's people like Jayann who make a difference. Thank you, Jayann, for always being so wonderful!

This review is just for the on-site tour. (have not used their services yet/was interested in seeing the facility first)
Made an appointment online and came in after work, just before their office technically closed. Justice didn't mind it was closing time and gave me the tour around and showed me two units I was interested in. Let me take some measurements and was happy to answer my questions. Appreciated the friendly service!
