Leave it to a gallerist to recognise a masterpiece when he sees one. After falling for Filicudi, Sergio Casoli transformed La Sirena into one of the Aeolian Islands' most charming refuges. Centred around the tiny piazza of Pecorini Mare, the property is a hybrid mix of hotel, restaurant, beach club and gallery, drawing a loyal crowd of artists, writers, sailors and in-the-know travellers every summer. Expect whitewashed Aeolian-style rooms overlooking the sea and Mount Etna on the horizon, plates piled high with the day's catch, and a front-row seat to life on an endlessly captivating islands.
