Truly the best place the stay in all of Sifnos! Kastro is the most beautiful little town and the apartment is next to the car park which makes it very easy if you have a car but also an easy reference point if using a taxi. The apartment itself is clean, comfortable and cool. Daily housekeeper service is an extra bonus.
I left my wallet there and Konstantinos arranged for it to be couriered to my next destination - truly went above and beyond! I would recommend Aegean Eye apartments to everyone I know and would return in a heartbeat.
