Needed a unit in a pinch and was able to get exactly what I needed that day. The two ladies at the front were very friendly and helped me find the unit I need. 5 ⭐️

An always-friendly experience at Guardian. Incredibly reasonable prices for the area, great staff and security. The units are kept clean, painted nicely, and I always feel safe no matter what time of day or night I’ve been there. Last week I lost all three of the keys to my unit, and getting a new lock installed was so simple, straight-forward and fast! It’s relieving knowing my belongings are this safe. Highly recommend!

I would have never factored customer service into storage needs, but the staff at Guardian Storage begs reconsideration. They're a model; they're great. A+

Everything about my experience with Guardian was seamless. From check in to check out, the staff members (Tammy and Wes in particular) were helpful, friendly, and very understanding. Would highly recommend to anyone looking for storage - short or long term. Moving is never fun, but they really go out of their way to make it as easy as possible.
