It’s easy to access, and everything has been well organized whenever I’ve needed to stop by. I also want to recognize Dustin for his excellent customer service. He was friendly, professional, patient, and took the time to answer my questions and explain everything clearly. It’s obvious that he cares about helping customers and making the process as smooth as possible. I would definitely recommend Extra Space Storage to anyone looking for a clean, secure, and well-managed storage facility with great customer service!

When I was moving out, I had forgotten my keys, and if the staff was not there to help me and cut it off, It would’ve ruined my day. He took the time to help me out, even though it was difficult to cut off both of my locks. Always liked it. It was always clean.

We are grateful the staff stepped up to help with your locks, Nicholas. Glad the facility was always clean and met your needs!
