We stayed 10 nights. The house is spacious, lovely, and tastefully appointed. Each room has its own character. The grounds enclose the house in a green, water-filled space. It's amazing having the mill stream (with a small waterfall) bisect the house between the kitchen/informal dining room (a large comfortable remodeled space) and the formal dining room. There is also a den (they call it a library) and a solarium (they call it a conservatory) downstairs.
The upstairs is also large. The newest bathroom, which is in the hall next to the second bedroom, is a marvel, sort of a Zen space with a French window and shutters that somehow works aesthetically. The second bedroom is one of the smaller rooms, but that's only because the other rooms are so large. The master (descending a few stairs from the hall) is huge, and like the kitchen and formal dining room, runs from the front to the back of the house. You descend a few more stairs to get to the master bath, which, although not as spiffy as the new bath, is quite adequate. I wish more American bathrooms had bidets (we used it to soak our feet).
Despite the high quality of appointments and equipment in the house, it feels lived in and comfortable. Peter and Elma, the caretakers, are pretty much always available by phone if you have questions about the house or the area.
Be sure to try Le Petit Restaurant (Peter and Elma's recommendation), a first-class restaurant in a nearby village. The cuisine is as good as some fine restaurants in Paris. Also, if you get down to Aubeterre, go to Crepes de la Sources, which has far more than just crepes and where we had an outstanding lunch. Closer to home is L'Olive Noire (in Mareuil) - excellent pizza made by one of the two owners and very reasonably priced.
Lots of stuff to do in the area. I heartily recommend Brantome, St. Jean-de-Cole, les Grottes de Villars, the Chateau de Puyguilhem (near Villars and the caves), Bourdeilles (magnificent chateau and scary castle tower), as well as lovely walks right in the area of the house (one is just on the other side of the back garden).
We had unseasonably rainy and cool weather much of the time, but if you have to be occasionally (we still managed to get out quite a bit) stuck inside because of rain, the moulin is a wonderful place to be stuck.
