This welcoming, original ecoconscious operation is a powerhouse of sustainable tourism, working with responsible local companies and using renewable energy, upcycled materials and fair-trade coffee. Minimalist dorms for four, eight or nine have personal power outlets, shelves and lockers; shared bathrooms are thoughtfully designed, with spacious showers and hairdryers. There are also private doubles, bike tours, yoga (€5) and an enormous terrace.
