Extra Space Storage on South Mills is a great place to store your things! Linda is so nice and helpful finding you the perfect space to meet your needs. Our unit is clean and protected. Even though it is 90 degree weather right now, the unit is not hot at all. Much better than a pod-type unit. Your items are very safe and guarded (gates, cameras, onsite manager) yet you can get what you need when you need it because the access hours are super long. Just check it out and you will see :)
