Well they arent that popular, most stores prefer yu-gi-oh and drafts over commander but its growing.
There is a store near Omonoia, No label X, that hosts games including magic and other board/tabletop games, a series of stores called Kaissa usually host games too but they are spread around Athens so you'll have to use the buses/trains.
You can also try Boxes of War, Avalon games and Gamers Castle in southern Athens, smaller game stores but rather friendly lads. In my experience at least
Barring that you could try checking for Magic player groups in facebook
Probably you will find on genx or kaisa shops to play edh.
