Alentejo Marmoris Hotel & Spa

The Stone Spa is carved into an old quarry cave, which tells you immediately what kind of hotel this is. Set in Vila Viçosa, a marble town near the Spanish border, the Alentejo Marmoris is a boutique hotel where the family that owns it has been quarrying stone for generations. Rooms lean Art Deco with a faint Moorish edge, bathrooms are predictably extravagant, and the restaurant gathers around a single-block marble table.
