Facility Overview & What to Expect

I recently rented a 5'x10' climate-controlled unit there and the entire process was fantastic. Price was competitive and the staff could not have been more courteous or helpful. The facility was built about 5 years I believe and it's state-of-the-art. There's an app that allows for incredibly efficient digital access to the electronic door and the overall building is remarkably clean. Access is 6am-10pm by default but I think you can get 24 hr access as well. In short, could not be happier with the place.

Mr. Anthony and Mr. Scott i’m not only amazing Customer Service representatives will they go beyond and above the call of duty to give extra extraordinary assistance thus given an amazing guest experience in a storage unit such as ExtraSpace Storage. Not for nothing both of these gentlemen, not only deserve an amazing bonus for Christmas, but they also deserve to be recognized for their dedication and hard work at ExtraSpace Storage.
