This recently opened farmhouse B&B, half way between Granada and Córdoba, is proof that you can go green without sacrificing luxury. The traditional "cortijo" has under-floor heating and king-size beds topped with Egyptian cotton sheets in the six bedrooms – plus a log fire in the lounge and swimming pool and hammocks in the grounds. However, the Biomas boiler runs on recycled olive pellets and solar panels heat the hot water.

Casa Olea, near Zamoranos, Priego de Córdoba (00 34 696 74 82 09; casaolea.com)
