"Occupying a particular niche on the Spanish luxury hotel scene is Castilla Termal Hoteles, known for turning historic landmarks — old university buildings, rural convents, abandoned factories — into sustainability-focused wellness retreats. The formula works especially well at Castilla Termal Monasterio de Valbuena, a luxury resort housed within one of the best-preserved 12th-century monasteries in all of Europe." - Tablet Hotels
