I had no problems.
My experience with iStorage Mullica Hill was good. They were willing to work with us. We do work for the banks and we store people's belongings for thirty days. I actually had forgotten about it. I called them and they let us come that day and get the stuff out because it was the last day of the month. So they worked with us on that. The only negative I would have, which is not really on them, is that they don't have 24-hour access.
