The beautiful coastal town of Porto Rafti (35 kilometers southeast of Athens and on the Aegean Sea side of Attica) is primarily populated with summer apartments and homes of Athenians. Consequently it lacks the commercialization. Consider this a benefit as you will experience what a native experiences and not the tourists of the islands.
Make sure to go up to the Kastro for a moonlit evening to see why this town feels like the Riviera.
