    Good enough

    Hard to get vehicle in space due to space between the drive and floor of the space.

    Ok but Lighting NOT Functioning!!!

    Office staff was very friendly. Facility is OK, BUT, three of the main flood lights that light the immediate area adjacent to my RV were NOT functioning!!! Additionally, flood lighting for the Business Signage was out too!!! Left message at office BUT have NOT received a return call several days later!

    Clean Units and Good Rates

    The unit I got was brand new, but all others I saw were clean. The monthly rate is very competitive with units closer to Waukesha.
