Nestled on a wooded hillside, this 18th-century Norman manor house overlooks the Seine estuary. Lush lawns with loungers and a pool lead down to the beach road. Drinks can be taken here, out on the terrace with water views, or inside by a roaring fire. Dinner is taken in a beamed, Michelin-recommended restaurant. There’s a spa, and 12 bedrooms have rustic-chic decor with panelled walls or patterned wallpaper depicting French country scenes, Persian-style rugs, elegant antique furnishings and sleek stone bathrooms. The manor was named after the impressionists who had a penchant for painting on this hill.
