This is a great place to get away from it all but still live in civilized luxury. Since the hotel only has a few rooms and is wonderfully isolated among the hills and vineyards, it's remarkably quiet. The best view is from the pool, which faces a gorgeous valley dotted with tiny villages. The owners of this chateau are extremely warm and welcoming, and they'll treat you like their personal guests. They brought us everything from history books about the region to American news reports.Everything about this place is lovely: the chestnut orchard, the rooms decorated with antiques, the fabulous breakfasts (fresh summer fruit from the local producers).
You do need a car to stay here, though. Bergerac, a moderately-sized city, is a few minutes away if you need any basics, and I recommend a visit to nearby Monbazillac, where they produce the famous sweet white wine.
In short, it was a memorable experience and I highly recommend the Chartreuse de Bignac.
