Helguera Palacio Boutique & Antique

A 17th-century palace in the foothills of the Pasiego Valley, restored into an eleven-room boutique hotel where the antiques are the decor, not the theme. The interiors lean into an old-money ease without feeling like a museum, and fourteen acres of gardens surround an indoor-outdoor pool with valley views. A small spa and a fine dining restaurant running Cantabrian tasting menus round out the picture. The Michelin Guide awarded it one Key.
