Pantelleria, the exclusive island that had a recent star turn in Luca Guadagnino’s A Bigger Splash, is now home to a retreat created by the owners of Coste Ghirlanda, a premier producer of this island’s cult Zibibbo wines. The 20 suites at Sikelia (www.sikeliapantelleria.com; from €400) were artfully fitted into a centuries-old complex of dammusi (the traditional domed stone houses) by the Milanese architect who designed Giorgio Armani’s house here. Pantelleria is closer to Tunisia than Sicily, which is evident in Sikelia’s cuisine (replete with African spices and inflections) and its spa, set to open next year in a Moorish-inspired pleasure garden. Up in the similarly sought-after surrounds of Positano, meanwhile, the owners of Villa Treville (www.villatreville.com; from €800) have taken over an old restaurant with rooms on tiny Laurito beach, reachable only by boat or steps and already home to Da Adolfo, the favoured trattoria of jet-setting foodies. Le Sirene at Treville Beach Club(www.trevillebeachclub.it; from €450) has eight stylishly simple accommodations (think bright white and cobalt blue, with tall French doors), a jovial beach scene by day, and by night, fine dining at the water’s edge – a pared-down but still chic counterpoint to its elegant sibling.
