high quality storage units, clean, with a good app to access the storage area (instead of having to use the keypad every time).service is friendly and helpful, although they sometimes have just one person covering multuple locations, so it can take a few extra minutes to get to talk to someone

Tammy and her staff at Guardian Storage in Boulder have been excellent to work with. We have rented space from them a couple times and both times the process was smooth and communication was clear. Also, the Guardian staff interact in a polite manner. This is always appreciated.
