    Easy access, safe place we put my husbands pride and joy in storage for the winter. His bass boat. So you know it must be ok.

    Late arrival taken care of

    Hello. Just wanted to let you know we arrived late and the manager had places to be as well, but had spent the time to make sure we could get in there that evening, which was critical for our plans not to fall apart. We were moving from Indianapolis to O fallon and decided we needed this unit last minute and she had taken care of us.

    Very Pleased! Wilma, the manager was helpful and courteous!

    The facility seems to be well kept and clean. Any concerns were mentioned and handled. i reserved a facility a couple of weeks before I needed it and they made sure my area was there when the need arose. Very pleased!

    The general manager was very friendly & accommodating. Allowing us to inspect the available units gave us the opportunity to discuss our budget & needs without the "sales pressure" of an employee breathing down our necks. Great experience!
