Here is a nifty little central Athens Greece map you might even want to print out. These 'Sky Maps' are sometimes available in Athens for @4 euros and usually show some ads but are nice to have even so. The good thing about classical Athens is that its all walkable from your central located Athens hotel (highly recommended). The Metro Map below is helpful too as the Metro authorities often run out of free maps during the summer months. You likely won't need the Athens metro map if you have a centrally located hotel but its good to have just in case. The metro now goes to the airport too!
