The sheets were washed and dried and put on fresh before you arrived! The apartment was vacuumed and mopped and wiped down from top to bottom too. We spent four hours cleaning the apartment before you checked in, so I don't understand your concerns. As I said, we do live in the flat normally so it's not a hotel and there are some books and personal items our ours around, but they were all put out of the way. And towels were in the cupboard as I mentioned when you came. Sorry you didn't find them !
As for the elevator, that's not in our control and very uncommon in Berlin anyway!
