Efthymia was an incredible guide and made our day in Santorini unforgettable. She was friendly, knowledgeable, and so easy to spend the day with. We never felt rushed; she was flexible with the itinerary so we could take our time enjoying each stop. She took us all around the entire island. We started in Oia for breathtaking views and photos, then to the ancient city of Akrotiri, to the Black Beach for one of the best lunches we had during our trip and then ended in Fira with plenty of time to explore on our own. Throughout the day, she shared the history of Santorini in a way that was interesting, engaging and easy to understand. We especially appreciated her recommendations and how she tailored the day to what we wanted to see instead of sticking to a rigid schedule. It was evident that she genuinely wanted us to have the best experience possible. This was one of our favorite days in Greece. I would absolutely recommend Efthymia to anyone visiting Santorini.
