Once an actual palace, this impressive residence facing onto Grande Plage, was erected on the orders of Napoleon III. It is every bit as palatial by nature as by name, with high ceilings, antique artworks, ornate detailing, chandeliers and regal furnishings. But floral prints, mod cons like blackout shutters and high-quality textiles ensure the 153 bedrooms also feel cosy. Amenities at this historic landmark residence include the Guerlain spa, indoor and outdoor pools, a playground, an outdoor eatery and the one Michelin-starred silver service restaurant Villa Eugénie (named after the wife for whom Napolean had this property built).
