Hell from Wisconsin,
Yes, very common in France, especially when renting from individuals.
The French have a six week vacation work year. And many vacation in France. I mean, who wouldn't with the beauty of the region, the history, and the FOOD. Many of the cottages are to rented Saturday to Saturday not by the night. The French can pack linens and beddings in their car and they are ready to go. For the owners of the cottages this is really nice. They don't have to do laundry after each rental. It keeps the prices down. And if you have visited the Gites de France web site, those prices ARE GREAT.
So far I have rented sheets are rented places that provide price included. I have considered buying sheets in Paris before we go into the countryside. And leave them with the last rental family. They would get a fairly new set for the price of cleaning them.
