Wow! Anxious about frantic day moving my kid out of the dorms, putting stuff in storage and catching our flight out of Denver, I was delighted by the streamlined process of setting up the lease, each with which I accessed to storage unit and more than anything, the incredibly friendly staff at the front desk. Highly recommend.

These guys were terrific in helping us determine our storage needs. Living outside of Boulder and not having the ability to be available for our movers to access our new units was a daunting thought. Wes made it easy for us to arrange pickup of our house key and access to the units for our moving company. Setting up contracts and using the online payment system has been a great feature for ensuring our property is safely stored.

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+
