    Chris was fantastic to work with! He remembered me from a conversation we had a week earlier, which immediately made the experience feel personal and welcoming. He was extremely knowledgeable, took the time to show me around the facility, answered all of my questions, and had me set up with the perfect unit in no time. From start to finish, the entire process took less than 30 minutes. I truly appreciated his professionalism, efficiency, and willingness to help. Thank you, Chris, for making the process so easy and stress free! Highly recommend. ... Read more

    I had an immediate need and they were able to satisfy with a great deal on a perfect size unit move in same day ready and great gate hours that are extremely flexible. However, my circumstances changed immediately following this arrangement and I was never able to get to that unit. It wasn't until I contacted Nicole the new property manager at this location and within 24 hours she had handled the entire crazy scenario that started 3 months ago. She resolved my account completely and I will definitely contact this company at this location for my future storage needs. Absolutely great experience thanks to Nicole! ?????? ... Read more

    PLEASE READ..... If your purchasing a storage unit won't auction. Best advice is Do Not . You will not receive your $100 cleaning deposit. It's been 2 months they said they have sent a check twice, now they say they don't cut checks. But they don't have cash either. They are scamming people out of there $100 cleaning deposit. They fail to hold up there end of deal . They lie right to your face. There fraudulent.. not an honest man in the building.. IF I COULD LEAVE 0 STARS.... It wouldn't be enough. [email protected].. is undeliverable. It's not even real. You have no intention of refunding my deposit. And I'm not going to stop. ... Read more
