Heather Shaver
Guardian Storage along with Christina make the experience and storage here fantastic! Christina is wonderful, she is very good at what she does! Storage units are all clean, and very nice! Couldn’t recommend more!
Sean hsu
Being a tenant for almost a year while moving. Everything works as it should. The staff are super helpful - thanks Christina! Well maintained facility - highly recommended!!
Kelly Graham
This rental facility is professional, caring, clean and takes some of the stress out of moving. They have the things needed from semi access for movers, locks for your unit, staff that are helpful in resolving concerns, and great safety measures. I can't more highly recommend them!
Response from the owner:Kelly, we are so pleased you enjoyed your visit to Guardian Storage!

I have used a lot of different storage facilities over the years and settled on this Guardian Storage location (Longmont). They have provided above average service the entire time I have rented here (3.5 years). I appreciated them keeping the property very secure and very clean the entire time. They also where very accommodating during move out and move in which can be rare in the storage unit business.
THANKS Longmont Guardian Storage!
Response from the owner:Thank you Sam! We are happy to help!

I had an exceptional experience with Christina at Guardian Storage! From the moment I walked in, she greeted me with a warm and welcoming smile. She was incredibly helpful, taking the time to explain all the storage options and helping me choose the best one for my needs. Christina made the entire process smooth and stress-free, ensuring I had all the information I needed and answering all my questions. The facility is clean, secure, and well-maintained. I highly recommend Guardian Storage, and Christina in particular, for anyone looking for top-notch service!
Response from the owner:Thank you Oliver!
