Terry at Extra Space Storage was extremely helpful! Moving is always stressful, and finding a storage unit that fits everything you need can be challenging. Terry made the entire process easy and gave us confidence that when our belongings arrive, we’ll have the space we need and a smooth move-in experience. We truly appreciate the excellent customer service. Thank you!

We’ve been renting a storage unit from Extra Space for almost a year and have had a good experience with them! They are kind and helpful and responsive, and are fair in their pricing. Terri was super helpful today in helping me figure out my move-out and final payment. If you need a storage unit, they’re a great way to go!

Clean, safe, monitored by cameras. Teri and the other woman in the office are amazing and do their very best to accommodate you and give excellent customer service. My downside is the companies financial policy. It was such a a great deal moving in it fit my budget (I'm 72 on a fixed income) but a few months later...bang you're hit with a $60 increase in rent. 😳 Then when I left, I was there for only 1 week into the month, they couldn't prorate my rent. But, I'll be eagerly awaiting the return of my deposit to help offset the cost of moving into a new apartment. All in all, I'd recommend them-- just check on your move out date time frame if you hope to get a little money back.

Terrible experience. Started out at a reasonable price for 4 months, then went up $100 for 6 months then went up $100 again! I was told it is to keep up with demand but that is BS, they are just greedy. I was able to move to a different location with a much better company for cheaper and it is an even bigger unit! They do not up the price unless absolutely necessary for their own costs. Tenants have been paying the same price for years. They treat their customers like family unlike Extra Space Storage. I will never use Extra Space Storage again.

I was in a rush to leave my storage unit and failed to slide the metal clasp all the way in and put my lock on it. Unfortunately the lock was not properly in place because the lock holes were not lined up. I received a phone call from Extra Space Storage informing me of my error. I am so thankful at the attention to detail provided by Extra Space Storage for looking out for my property.
