Booked George's Taxi for transfers to/from the Savoy hotel and airport. BUT during the stay discovered that the subway system is within a very short cab ride from the hotel. The trains go right to the airport and shopping areas. The only consideration is luggage. We had one carryon backpack each so we were very mobile. It was easy breezy. My only caution when taking public transport is to get directions. know the name of your stop. I found that often the stops went by 2 names. The folks at the terminals are VERY friendly and VERY helpful with this information. Inside of the train cars you will find a map with a light that illuminates for each city as you approach. Nothing to be nervous about jump in! Oh and if you are going to the Acropolis and/or Museum you can do this by subway as well. FAR cheaper than cabs. It takes a bit longer but it's a great way to see how the locals live.
I booked a cab online on Athenstaxi for around 65€ for 6pax, took 50 mins to reach airport.
Get a taxi and go to the train station in Piraeus. From there get instructions in how to get to airport. It is not difficult at all and above all, cheap.
