If you're looking for a quiet place to relax and unwind, this is definitely one of the best options on Kea (and probably in Greece). The location is a picturesque 15-20mins walk from the port of Korissa, where there are shops, restaurants/bars, and a bus stop to take you to other places on the island. It's also easy enough to rent a car or a motorbike if desired, though keep in mind that some of the roads aren't paved.
Most importantly, the villa sits about 3mins from one of the most secluded and beautiful beaches on the island (rarely more than handful of people there at one time). There's also an overlook nearby that provides a great view of the sunset and surrounding coastline.
The villa itself was very nice, clean, comfortable, spacious, and had everything needed for a holiday! During my stay, Mary was incredibly helpful with any island suggestions, queries, and bookings, and ensured that my time on Kea was absolutely perfect. 14/10 would go again. Hopefully will return soon!
