Dimitris was a wonderful guide! The only reason I rated 4 stars is because there was an issue with his headset and sound cut out to those of us sitting in the back of the van. Dimitris was very attentive of the issue though and did his best to keep it working. Dimitris is very knowledgeable and provided so much information regarding the sites we hardly needed to ask a single question. He is easy to understand and very personable. We would highly recommend this tour! Fantastic day, thank you Dimitris.
