If anyone fancies visiting somewhere just that little bit different and special this year, can I recommend Sesto Hill Bar on the way down to Koroni beach. It's about half way down the track to the beach, passable in a car, and is a fantastic place to watch the sun set over a glass of wine and some souvlaki. It's very rustic in feel and is in such a fantastic spot, almost perched on the edge of the hillside overlooking Koroni bay.
You'll get a warm welcome! They do put on special evenings of Greek music or film nights too, and you can keep an eye out for these listed on Facebook on their page there.
I have no connection with Sesto Hill Bar at all, just wanted to recommend them as I've had a couple of great evenings there. Truly breathtaking views and lovely food.
