Robin Higham
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
Response from the owner:Robin, thank you so much for the wonderful feedback. We're glad the Guardian app is making your experience more convenient. We are always here to help so please let us know if we can help in any way. Thank you and have a wonderful day!
James Brittelli
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.
Response from the owner:Please don't hesitate to reach out if there's anything additional we can do for you. Thank you James!
