My experience with Cubes Smart Storage has been great! Site is clean and secure. Haven't found any rodent damage to any of my stuff over a span of 3-4 months. My only complaint is that they don't prorate your rent. I didn't get the keys to my new house until 2 days after storage rental due date, this was totally out of my control but had to pay the whole months rent. They told of this at the beginning though, but I dislike the practice...

I recently had a strange experience with my storage unit. Your whole staff was very helpful and understanding in coming to a solution to something that not only shouldn't have happened, but shouldn't have been possible. Thanks guys, you made a long wait and a stressful situation much better.
