Makis was an amazing help for us. I recommend him 100% for your travel needs in Santorini. He is a local who was born on the island and offers transportation services. We were lucky enough to run into him when he had some time to take us to the port, but we were so happy to have him as a driver and listen to his amazing knowledge about the island. Definitely contact him to schedule pickups/dropoffs and tours of the island, It is so much better to tour the island with someone who can tell you so much about it!
