October 22, 2026

The property is clean and seems well maintained. Andrea, who helped me get checked in, was great. She is friendly, pays attention and helpful. There were a string of extra charges that are quite annoying. Andrea took the time to explain them, all done with a smile. The manager, John, is a great guy. A welcome change from most self storage places. He is friendly, remembers me and always helpful. .

Thank you immensely for your feedback, Adam. We're glad Andrea provided excellent service and you found our facility clean. We apologize for the manager's unprofessional behavior and will address this immediately.
