The CP website indicates that the airport is about 29 km from the airport, for a 35 minute ride. They claim the taxi charge to be 25 euro. I feel, that
would be quite low and unrealistic, especially compared to London or Paris. Also, I am never comfortable with taxis from an airport to any destination that I have yet to experience, because one does not have a reference point yet. I remember how I got screwed in Bangkok the first times until I had things under control. I know nothing about Athens, so maybe I feel more inclined to use the bus or the subway. Also I don't speak Greek and I have no idea how their English speaking abilities are. That's always a good reason for taxi drivers to cheat or at least try to. By the way,are the signs in Greek and in Western characters as well?
