    Wilma (and Izzy) have been the greatest to work with! She has always been helpful and supportive with anything I would need. Being a vendor, I would have orders delivered to my storage unit. She would help with communicating when deliveries were made and made me feel welcome every time I showed up. Not to mention, her puppy is the cutest thing I’ve ever seen ?? 10/10 service and reliability. Would HIGHLY recommend! ... Read more

    Really enjoyed the first several months at this location. Unfortunately, as a few other reviews noted, my price went from $91 to over $140! I was told it was an introductory offer, but that was in no way made clear. I was in a smaller unit and moved to a larger unit due to the fair price. With all the new storage facilities in the area, there is no reason for me to pay this exuberant cost. It makes more work for me to move, but I can cut my cost in half. Will be sad to go, but to pay that much more and receive nothing more in return is silly. ... Read more

    *DO NOT RENT* UNLESS you are in a bind for two months. It's a scam. They bring you in with 2 free months then the agreed price of $79 for my unit Then shortly after, raised the price to $125 a month without my consent. It is never discussed. They just send out an email before rent is do. I called and asked to but was lied to and was told its just a early reminder if the bill is late. Then the payment comes out of your account and they tell you that's your new rent. This is sneaky and underhanded. ... Read more

    We just walked in and Wilma was very friendly. She kindly showed us different units so we could get an idea of what a 10x10 looks like. We loved that it's gated and requires a pin code to get in and out. We went ahead and signed for storage today. Thank you! ... Read more

    Outstanding manager. Extremely friendly. Great little dog. The best storage facility than the big named brand storage facilities that’s taking over. Owner owned and not company owned.
