Read some helpful reviews of Diamond Self Storage, shared by real renters with genuine experiences and honest opinions.

Don’t waste your money with this company! They switched over from a pin pad enter/exit system to now you have to call a number. 3 times over the last month the gate would not open and I have been unable to access my storage. When I went inside to let them know the situation the lady at the desk was very rude and had an attitude from the beginning, not apologetic at all! More like I have no control, sorry about your luck it’s the cell phone towers fault. Very unprofessional! ... Read more

I called Heather at the office with an urgent request for an additional storage unit. She had everything ready for me at the time of my arrival. I was in and out. Upon entering both of my units for the first time, each were very clean and ready. Thank you, Heather! ... Read more

Man let me tell you, the girl that works there and who runs that place is all the way awesome and really on top of everything. She helped us out with everything we needed and even things we hadn't even thought of. The place is clean and very affordable and cheaper than most every where else and they have a deal going on that you only pay 100$ for the first 4 months and then it goes up just a little depending on what you got. I highly recommend this place mostly because of the really nice girl that's running the place and because of the price. ... Read more

Update: they have since refunded all of the excess charges with no explanation action. $500+. However they are family owned so no one is held accountable for the misuse our our card information. Horrible communication and availability! They charged an extra $185 AFTER we paid $400 for two units! Then they don’t answer the phone about this! Also they are allowing SEVERAL car repair businesses out of units and we checked on our unit and could smell burning from the other side while they were working on cars. What if this place catches on fire? HORRIBLE BUSINESS! Unsafe and they debit money out of no where with no receipt ... Read more
