we used extra sheets as there're two of us and only one bed was preparied. Before leaving we rearrange sofa and put used linen in the bathroom. We also left containers with clean linen in room so you can see that we took some sheets from them. But no linen was on the floor. We also left apartmnet with clean dishes and no garbage.
I had two dozen stays and no compliments about cleanliness, so I'm really surprised. I suggest you met guests personally if you have any special requirements or add your requirements in aparment description...
