Dimitris was charismatic and engaged on our tour of ancient Corinth. He was flexible with our requests and eagerly agreed to meet us at the top of the mountain on short notice. He helped people in my group climb over the slippery stones and has experience as a mountain climber. In addition to history, he provided great information about the local flora. I think his tour would benefit from a cohesive narrative binding his expansive knowledge. I would take a tour with him again.
