Love it so far. Locked my door in the open position and extra space called me the same day to let me know to fix it. Good customer service.

My dad recently got a unit here. It has been nothing but a positive, pleasant experience. I am extremely happy with the customer service and treatment both of us have received! Thank you!

This place has worked with me and helped me during my move. I called today to make a late payment and Joel was kind and made it very easy while answering my questions. When I need to store things again, I'll definitely come back here and recommend to friends as well

These guys are so excellent to work with - incredibly kind, competent, accommodating, and professional. They're going through some issues with construction at the moment which limited access for a while, but they're handling it really well.
