5x10 storage units are a great solution for a wide range of short-term and long-term self storage needs, including moving to a new home, storing college dorm room items, using storage while deployed, and decluttering a house or apartment. These units are comparable in size to a walk-in closet. 5x10 units can typically hold the contents of a small bedroom or dorm room, such as a queen-size mattress set, dresser, TV, and several boxes.

I just secured a storage unit here last week and I’m already really happy with the decision. The whole process was smooth and straightforward — from checking availability to signing the agreement and getting my unit, everything felt quick and professional. The facility is clean, well-maintained, and the unit itself is in great condition. Access has been easy, and the staff I’ve interacted with so far have been friendly and helpful. It feels secure and well-organized, which gives me peace of mind. If you’re looking for a reliable storage option, I’d definitely recommend this place. Glad I chose it!

We are grateful for your kind words, Tanner! We're glad the process felt smooth and professional, and that the facility meets your expectations.

Space is newer so its nice and clean. Set up and move out were a easy. That being said, the hours of operation listed online are not the office hours. Apparently they are the corporate customer service phone hours. So I drove to site based on the hours listed online and had to wait (staff were there in the parking lot but office was not yet open). On one occasion I loaded boxes in my car, drove to site, unloaded everything, went to open the door and apparently an electrical issue caused all of the doors to malfunction. So I loaded everything (in triple digit heat) back into my car and drove around to the office. The staff walked me outside to test my entry code and app, both of which worked properly but the doors wouldn't open. They acknowledged they had an electrical issue and a vendor should be there to resolve soon. Their solution was for me to go door to door seeing if any of them worked …..instead of perhaps opening them from the inside. Once the issue was resolved, that was not communicated. I called days later to confirm the doors worked before driving back over there.

Thank you for sharing your feedback, Kylee. We're glad to hear you found our newer facility clean and that your rental and move out process were easy. We apologize for the inconvenience caused by the confusion around office hours and the access issues you experienced. Your feedback is valuable and will help us improve the customer experience. Thank you for choosing Extra Space Storage.
