We were fortunate that our hotel contacted Christianakis to provide transportation for us from Piraeus to the hotel in Athens. They provided a high quality, new van for the 6 of us that was very comfortable. Our driver was great. He was professional and spoke English very well. We quickly decided that we would like to have him give us a tour around Athens for a couple hours and Christianakis adjusted their schedules on short notice to make this possible. That tour went so well we also booked him again for a day tour the following day to see the Peloponnese peninsula. Overall outstanding service and value provided by this company.
