We stayed in Stergos apartments for 4 nights on August. We lived in a flat on second floor with balcony on the sea side (sea is just few hundred meters away). Beautiful view and freshy wind from the sea + the flat most of the time was in shadow - because of that we did not use conditioner even once. Although it was very hot outside - the temperature in the flat was always very comfortable.
The flat was very clean with everything needed. After living in Stergos' apartments you can definitely say, that he loves what he do.
There are two markets in a kilometer radius near the place and lots of rent services. You can rent a quad or a buggie and visit most of Kos sightseeing within few days.
Anthia Apartments is best for relaxing from big noisy cities and enjoy the nature. Definetely recommended!
