We flew in to Santorini just for the day. There is no way we could have done in a day what we did with Ioannis. He took us to great photo stops but also Oia, Fira, Akrotiri, the Black beack, a great lunch place and ended at Santos winery. We drove through several other cities and he pointed out history. Great tour and highly recommend him or any of his guides (he is the manager).
