We stayed at the Aegeon Beach Hotel and really liked it. We were traveling for 6 weeks in Greece and headed first to Sounio, since it was fairly close to Athens but quiet and with a beach - perfect place e to recover from jet lag before we began our more serious travels., The hotel is modern, good a/c, parking, a generous buffet breakfast with fabulous views of the Temple of Poseidon. The beach is sandy (brown sand not white), with very gentle waves; lots of lounge chairs. There are also two restaurants I(quite good with basic standard Greek fare, especially seafood) within walking distance. To do? Hike up to the Temple, swim and do very little though, one day, we did venture to the National Park (which is huge) and to the town of Lavrio. We were the only American guests (in September). Do go - it's lovely!
