September 06, 2023 - From Extra Space

This Extra Space Storage facility is clean, modern, well secured, and in an easy to access location. However, the highlight of this entire facility, is Heather. Heather has provided the most amazing customer service that I've experienced in a very long time. It's that small town kindness that makes you feel welcome, and you know you're in the right hands, with someone who's going to take care of you. Heather's experience, help, guidance, and politeness, has made this facility shine the most for me. Cheers and thank you.

Heather was a huge help. Although they did not have the size space we needed, she went out of her way to contact sister facilities, and send us in the right direction. She is definitely poised in customer service. Thanks for your patience and guidance.
