In 2008 we enjoyed "Le Moulin de Paulhiac" near Daglan. It's near to the interesting sights, e.g. Sarlat, Domme, La Roque Gageac but still very rural and quiet. Nice sanitary facilities, although little separation for the sexes from what I remember. Superb pool, restaurant, small river to swim and fish, and helpful owner. He didn't speak any English but his wife was fluent. Just opposite the site you can walk down a dirt track for miles into the wilderness. Mostly Dutch on site plus regular Brits who go back year after year.
