We scheduled this tour for a group of 5 and could not have been more pleased with the tour. Petros, our guide was knowledgeable, interesting to listen to, and made sure we got to see the high points of Santorini in our short cruise stop. Our driver was excellent and we felt very safe with him at the wheel. The island was quite busy as there were a number of ships in port, but Petros got us out to some quieter areas where we really got a sense of the culture and history of Santorini. Highly recommend this tour.
