This sylvan retreat at the base of the Carpathian Mountains is set amid what was one of the largest privately owned forests in Transylvania until confiscated by the Communists in 1949. Now restored to the Mikes family, the estate is being rebuilt using funds raised from the guesthouse, restoring more than 60 species of trees and a vast artificial lake. A 16th-century outbuilding now offers simple, elegant lodgings.
