    David S. - 6 March 2025
    Being that this is our first experience with the need for self-storage, we decided to visit a few locations near us. Extra Space Storage was our first and ONLY stop. Upon entering the Riverside Street office, we were greeted by Trisha the Store Manager. While being escorted through the facility, Trisha very kindly explained the features they offered as well as answered all of our questions. Trisha was awesome and the facility was clean and in exceptionally good condition. As a result, we decided this was the place for us and I am very pleased with our decision to secure 2 storage spaces here. Thank you, Trisha. ... Read more
