    I have rented from this company for over 5 yrs! When it was Cube Smart. This newer company is by far the worst. The way Scott talked to me today is the worst i have ever experienced as a customer. I asked him for his manager number he said there is no one over him. He yelled and hung up on me!!! . I really hope this reach someone in corporate to listen to the call and get back to me ASAP since he would not give me anyone I could reach out to. I will be reporting this company to the BBB. PLEASE DO NOT RENT FROM THIS PLACE! FYI I rent from the S Kingshighway location, they were closed today so my call was redirected him He would not give me his location nor did he want to give me his name. However, I found him!! Forcing people to leave good reviews is insane because I know he talks to customers like this often. Needless to say he found the right one because I will not stop until this is resolved. ...

    I’ve had nothing but bad experiences everywhere else, this place has been amazing! Everywhere else we’ve rented has raised the price over and over again by a lot, and when I first started renting this place, I addressed that with them and they told me exactly when they raise their prices and why and so far it’s been exactly right and they only raised it by like 10 or $15 compared to these other places raising it by like 50 I absolutely love this place though and all of their stuff is temperature controlled and secured very well. And I’ve been renting here for going on a year now. ... Read more

    Scott Simon was fantastic to work with. He found us the right unit and made it very easy to set up. It was a temporary situation for us, which meant we cancelled the unit after a few months. Scott handled the cancellation with the same kindness and professionalism as when we initiated the rental. We would use this facility again without hesitation! ... Read more

    We just switched another storage company that did not offer climate controlled storage. This facility is amazingly clean and very secure with 24 hour access. The best thing is the price. I could not find a lower price for the same size and type of storage anywhere in the St. Louis area. We also found the Mgr.,Scott Simon, to be very professional as well as very cordial. If you need clean, climate controlled storage this is the place! , ... Read more

    Frequently Asked Questions

    The right storage unit size depends on what you plan to store and how much space you need to move around your items.
