My wife and myself stayed at Chateau de Buffavent while traveling from Belgium to Spain ... and it simply blew us away.
Located only 5 minutes from the highway, it couldn't have been further away as it was an oasis of peace and quiet. The hosts and their family made us feel right at home, and the delicious food and wine did the rest. The surrounding garden and winery (did I already tell the wine was very good indeed?) provided a nice and relaxing environment, just what one needs after too many weeks of stress.
Is language a problem for you? Don't hesitate to ask anything ... the family is there to help you and provides you with some nice tips for the region.
In short, I would dare anyone to go there and not go away relaxed and with a smile... and would warmly recommend it to anyone who is willing to join in a good conversation over a glass of wine.
