Torre del Marqués Hotel Spa & Winery

What the classifiers highlight

An 18th-century tower in Aragón's Matarraña region, between Barcelona and Valencia, holds just 18 rooms, weathered stone walls set against sisal rugs and knotty pine paneling, looking out over olive groves and vineyards. MICHELIN gives it three Keys, and the spa runs on hot springs with a Turkish bath, rates staying under 300 euros a night despite the rating.
