Wohlfahrtsmühle Waldhotel & Restaurant in Hardheim, Baden-Württemberg. Nestled among forests and meadows by the old mill stream, Wohlfahrtsmühle offers a rural idyll like something out of a picture book: absolute tranquility in the Erfa Valley in the Odenwald. Until 1968, the grain of local farmers was milled here. The buildings have since been transformed into a modern country hotel where old and new harmoniously unite. Wohlfahrtsmühle has been chosen as one of the most beautiful country hotels in Baden-Württemberg.
