The sophisticated Penthouse Suite at Mandarin Oriental Barcelona has been decorated in shades of mink, white and gray, and is dotted with bespoke furnishings and contemporary artworks. Ideal for entertaining, the Penthouse Suite has a spacious dining area with room for eight guests and an expansive living area. The pièce de résistance, however, is the sprawling outdoor terrace — a gorgeous setting to relax with a cocktail and watch the sunset over the city. Occupying the entire top floor, it's the perfect suite for those in need of complete discretion.
