We have use Extra Space Storage for a number of items, including our RV in the Winter. Fair price, clean, and easy access if we need to get to our stuff. The app is great and the gate control is built in. Very convenient to not have to carry around keys or remember multiple codes for multiple locations.

We needed a place to store most our belongings while looking for a house. Rt. 12 storage accommodated us easily...offered auto bill pay, and was hassle free.
Unit was clean, never had an issue with rain or snow over the 6 months we were there.
