Good: Not a thing. Have to give it one star because can't give it a zero. But if I could I would give it ZERO stars. Bad: Storage units leak, Floor get wet in winter when Snow gets piled up next to door. Everything gets dirty in summer because door seals are bad. Owner want big bucks for these units and you can't access your stuff after 9pm without paying $30 for an exit code. Improvements: Who cares? I'll never use this place again and would never recommend to anyone else.. Other: There are plenty of better storage places in the Whitmore Lake Michigan area that are cleaner and cheaper. I would not go to this place EVER..
