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. ... Read more

    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. ... Read more
