Areias do Seixo is a modernist glass and concrete construction located on a protected patch of Portugal’s Costa de Prata, just 30 minutes north of Lisbon. 14 uniquely designed bedrooms are equipped with polished cement floors, pebble walls, soft quilts and sleek hanging stoves, relying entirely on geothermal energy and solar power! How would you love to escape to this intimate oasis for a few days?
