Alice was so helpful when choosing my new storage unit. She was very informational and guided me every step of the way. All of my questions were answered and I felt very comfortable choosing this as my secure and safe storage. I highly recommended getting a storage unit here if you’re looking for one!

This location provided me with the best service. Alice was quick to answer all my questions and even offered to make me a reservation so I could lock in the quoted price I was given while I took a few days to decide whether or not this was the right place for me. I'm glad I chose to stay as the facility is very clean, temperature controlled, and very accommodating.

We decided to go in person instead of doing the unit online to compare sizes. Alice was great help showing us two different size unit and explaining the difference.The price was great. Also gave us a unit that was close to the door for my mom that is disabled, so she can access the unit easily. Would definitely recommend Extra Space storage on Miller Rd in Buckeye.

Made a last minute decision to book a storage unit for things we were packing up mid move. I was able to get access to my unit and start packing boxes into storage 30 minutes later. Staff was friendly, clean units, key provided for an additional fee, and PIN code access into the building. It’s been a nice experience so far!
