Steve is one of the nicest guys you could meet. He helped me with a bunch of questions that I had and was very hospitable. Extra Space should consider themselves damn lucky to have such a piece of gold like this guy. You better not let him get away, Extra Space!

Brian made the sign up so easy!!! He was very polite and patient. He answered all of my questions and made sure I understood that I could reach out any time if I had any questions. He explained everything in great detail. The big plus was that he was not pushy and did not try to sell me anything I didn’t think I needed (which is something I was sure I would encounter). Great experience so far!!!

My husband and I needed a place to keep some of our stuff after downsizing, and rented a unit from Rt-12 Storage for a little over a year. The facility is easy to access, well-maintained and secure, and the staff are so helpful and friendly!
We will definitely go back to Rt-12 Storage next time we need a storage space.
