We spent 24 hours at this hotel (a Logis de France) which we happened upon as a result of a good review in Guide Routard. The review was well justified. The hotel was very comfortable, run by a very friendly and efficient couple (who speak excellent English), and the food was excellent and reasonably priced. We had a large, well-equipped room with a beautiful view across the lake and hills.
Cieux is in the Monts de Blond, a very pleasant area for walking and relaxing, about an hour west of Limoges.
