My first experience using a storage unit was with Guardian Storage Westminster and it was a breeze from start to finish. Mark and Erica (not sure if she is still at that location) were absolutely amazing and provided superb customer service . The entire facility is clean and safe! All my belongings were in the exact same condition after a year! Thanks so much!

The people here were so helpful! They helped us set up storage in October. We closed and moved into our house during the new years but they helped us work around their holiday hours. There are carts a plenty, 4 each in each bay plus some in the little entrances. Elevators are huge and 2 carts can fit if nothing is oversized on the carts. Will use them again if storage is needed!
