One travel advice for Greece, if you choose an island, choose one without an airport. It is so much more charming to stay on a Greek island that is only reachable by boat.
Seeing the ferries arrive and leave again in the small ports always give me a sense of remoteness, being far away from the rest of the world. It reminds me a bit of the thrilling sensation of airports.
Same here on Sifnos, when we see our favorite boat, the Adamantios Korais pulling into the small harbor. 7 Beaufort plus, and she is still sailing the Aegean Sea.
