Adrift in the Mediterranean Sea, the French island of Corsica has been influenced by its proximity to Italy, as is evidenced in this 17th-century, Florentine-style palace. Completely refashioned by interior designer Nathalie Battesti, U Palazzu Serenu is made for modernists, with its sleek furnishings and intriguing art collection. Exclusivity is the defining characteristic here — there are just six guest rooms and three suites, and the tranquil dining venue hosts no more than 25 diners at a time. In season, guests enjoy the restaurant's Mediterranean cuisine and a wine list of Corsican vintages on the terrace with views of the Gulf of St. Florent. With its breathtaking style, lap pool, wellness area and location just a short plane ride from Paris, this hotel provides an extraordinary island escape.
