Design here, though, extends well beyond what you can see. Sound is curated by Marie-Louise Sciò herself, with different tracks for different spaces, adjusted through the day. At Hotel Il Pellicano, the scent of rosemary, native to the surrounding hillsides, permeates every outdoor space and has been extended into a full line of soaps and creams. At La Posta Vecchia, the new pool dialogues with the glistening sea out front, creating an almost otherworldly sense of being suspended between water and sky. At Mezzatorre, thermal water drawn from the hotel's own private spring flows directly into the spa pools, Ischia's volcanic geology, quite literally, becoming part of the guest experience.
