Tim was incredibly helpful over the phone and even more phenomenal in person later that same day. We got everything squared away immediately with no issues.

I had such a great experience renting a storage unit here! Tim was so nice and went out of his way to walk me through the entire lease process, making sure my daughter was added correctly. Excellent customer service!

I came in earlier today for the labor day deals on units and met with the manager Tim. He was very kind and showed me through the unit types I was looking for, both indoor and outdoor, and explained the differences with plenty of info on everything I needed to know to make the right choice. I'll be recommending anyone to this location for ease of access to I35, the cleanliness and solid management. A+ Extra Space Storage!
