September ushers in a calmer, cooler, rosy glow over the romantic island of Santorini. The summer rush is over, the sea is warmer than ever and the skies are a pure Tiepolo blue. Autumnal sunsets paint the town of Oia gold, casting a glimmer over the azure Aegean ocean. Santorini is home to many luxurious hotels adorning the craggy coastline, many with private pools or your very own hot tub. The Grace Hotel is famed for its infinity pool and endless ocean views.
