On a tree-studded peninsula between Monaco and Nice, this whitewashed luxury boutique hotel features 28 rooms and suites with a serenely chic vibe (think crisp white linens and richly patterned textiles, contemporary art and modern streamlined furnishings). A third of the units reside in the hotel’s main building, a mansion that dates back to 1889 but was fully restored and updated in 2003, and three additional rooms designed to resemble ship cabins are built into a wall with direct views onto the sea; the rest of the accommodations are housed in a quiet Italianate structure and a separate edifice at the edge of the property. Cap Estel’s Michelin-starred restaurant highlights seasonal ingredients, many of which are sourced from the on-site gardens. Guests who come to disconnect from the jet-set scene can relax in the hammam or waterside sauna, or with a massage and dip in the saltwater pool, though many guests would just as soon head straight into the azure waves of the Mediterranean, accessed through the hotel’s private beach.
