Carri Ann was great! Super efficient and friendly. She met with me at location and was super helpful. Very impressed with new owners and staff.

The Extra Space Storage SW site manager, CarrieAnn, is awesome! She is professional, friendly, knowledgeable, and finds every way to best accommodate the customer!
The directions to access the unit were fine and the unit is as expected.
I would definitely go back for future storage needs based on all of my interactions with CarrieAnn and the reasonable rates, flexibility, and location options.

CarrieAnn was the BEST to talk with. First time storing dorm room items from across the country and she answered all my questions - even clarified if I needed it to be repeated or misunderstood. She provides all the details for what to expect when moving items in and out. Thank you!!!

We added another unit. Carrie Ann took the time to find us the unit closest to our current one and ensured everything was correct on our account. It was a seamless experience.

Carrie Ann is always so pleasant! I was going to move my belongings out of Extra Space due to the pricing going up. But Carrie Ann in south windsor got me a great deal! Thanks to her I just switched locations rather than storage companies! She’s awesome and always has a smile. 😃
