It is not often that we do holiday rentals but when we do, the place is always left in a clean and tidy state.
As for the bedding, unless requested, we don't strip them but leave the bed linen turned down tidily so the bed can air. Sometimes we have stripped the bed - if we have time.
On a cruise ship DH works on, we strip the bed on the last day of the sea contact - cabin stewards are very pressed for time especially when it is a turnaround port. In between, we keep the cabin tidy so that our poor cabin steward can get his work done without hindrance. We have heard (Chief Housekeeper letting off steam) about the state of some of the cabins, including entitled people expecting cabin stewards to fold and put away clothes
, pick up dirty underwear
, etc.
We are always respectful of any place we stay in.
