Unit was clean when we arrived. Day 2 we noticed unit was not cooling down. Called maintenance and it worked a little better. The sliding door to the patio is broken and should have been replaced long ago. It was all I could do to open it. Called maint. and the first time they came they must not have done anything. The second time I think the supervisor came, looked at it and wrote me a note saying it needed to be looked at by a pro door guy.
