Joanne,
You might want to check out this link,
George, the famous taxi driver of Greece . He charges 35 euros fro the transfer from Pireaus to the Grande Bretagne.
We will be using him on our upcoming October 16-October 30 Monte Carlo to Athens SilverSea cruise. We will also be staying at the Hotel Grande Bretagne for a couple of days after the cruise.
Enjoy your cruise! We are certainly looking forward to ours.
