    What a wonderful storage facility. We have been there several years and are always impressed with how clean the facility is. When we moved our possessions out because of moving to a different state we were again impressed with how clean the storage unit was as well! I highly recommend using this location (Mt. Vernon Avenue, Milwaukee).
