I went…read moreon the 10 hour Athen city tour, the 10 hour Ancient Corinth and Nafplio tour, and the 10 hour Delphia tour. All the tour guides were professional, knowledgeable, and friendly. The tour to Delphi was extremely enlightening. My tour guide Marrianna Tsigaridou was so knowledgeble and entertaining she was absolutely amazing in her ability to clearly communicate greek and european history. Also, all the restaurants they took me too were amazing not one bad meal: food was well prepared and restaurant staff was very friendly.
