Once the bayside palazzo of a shipping magnate, the recently restored Romeo juxtaposes antique and modern art in a world-class collection. Fabrics, serving pieces, and porcelain by Hermès, Andrée Putman, and J.L. Coquet complement the Kenzo Tange–designed facade of undulate glass. Doubles from $240, 39/081-017-5001.
