My experience has been pretty good!
I recommend iStorage Laceys Spring quite a bit. I drive a truck and can get it right across the road and up to my unit. It's easy access getting in and out: that says it all right there.
I've been storing there for three or four months now. Do it! You can't go wrong. The customer service has been really good. The people have been friendly and are always nice. They talk to me when I'm there if I see them. I have no problems with them.
