Fira, the capital of Santorini, continues north into Firostefani and then Imerovigli, the highest point on the caldera rim. The area is livelier and better connected than Oia, with views of the volcano and its islets. Our selection covers these three villages: shared heated pools and private jacuzzis. I've selected 35 places, all rated at least 8/10; the top-rated is Two Bedroom Villa with Outdoor Heated Plunge Pool (4.93/5).
Each city has its own selection, with a page for each type of accommodation.
Places are ranked from highest to lowest rated. The yellow bubble shows the advertised water temperature, when it's known.
