My experience with using Guardian Storage was very good. The front desk people were very professional and I didn't have any issues with them. The entry fee is reasonable but people should budget in a fee increase at 6 and 9 months after the start date for a storage unit.

Friendly, helpful and knowledgeable staff. They offer a page or two to print, and wifi. While you are, at the office.The site itself: Very clean and well maintained. Security devices, and staff awareness, make it safe and secure.Location is at the end of North-Boulder.

I needed to store my belongings while I was in-between apartment leases and Guardian Storage was very easy to work with. Denise was very helpful! Thank you!

Overall a pleasant experience renting with Guardian. Unit was clean, felt secure and well lit. Use of the truck was an added bonus too, came in handy a couple of times as our move happened in increments between houses.Only complaint was the sign up process which was overly burdensome. Do some paperwork, sign something on the iPad, more paperwork, copies, iPad again, more paperwork...everything just seemed redundant and not efficient at all. That process needs improved but otherwise a pleasant experience.Lastly, I can't recall the manager's name at the moment (summer 2019) but he was very friendly & helpful.

We needed temporary, climate controlled storage after a basement flood. The facility in North Boulder provided us with easy access in a clean state of the art facility. The staff was efficient and friendly.
