Kalliopi was a fantastic tour guide. She will work with you to see what you want to see and also make suggestions if you don't know where to begin. She had an answer to every question we asked, and it was clear she is very passionate about Greek history. Overall very enjoyable, professional, and worthwhile. The communication was also great leading up to the tour, and I never felt unsure that she would show up or I wouldn't be able to reach her.
