We really enjoyed our stay at the appartment! It was modern, clean, private and comfortable. The groceries in the fridge that we found at arrival were suprising and really appreciated!
We would definitely recommend to stay in this or another appartment of Constantinos! For your stay, we would recommend a car, because only (walking in) Kolympia itself was not that entertaining to us. With a car you can go to (other) nice beaches and the grocery shop real quickly.
