Ancient meets modern in dazzling style at Rouen’s only five-star hotel. Step inside this 15th-century mansion by the place du Vieux Marché and you’re immediately in one of the most modern and chicest hotel interiors in the region. The galleried Atrium Bar makes a bold statement with its soaring red ceiling and glass floor exposing the spa’s enormous indoor pool below. No two rooms are alike: Some have sleek, minimalist decor while others go for the full traditional look with antique-style furnishings, exposed ceiling beams, and wood-paneled walls. In addition to an indoor pool, the Spa du Drap d’Or features a steam bath, sauna, a fitness room, and treatment rooms.
