A Greek island in the Cyclades group in the Aegean Sea, Mykonos is famous the world over for its exclusivity, jaw-dropping hotels and signature white-washed streets. Broken up by the blue window and door frames and other eye-popping accents, Mykonos' streets might just be the most beautiful in the world.
