I, my wife and son (two years old) stayed for couple of days in Ano-Symi. Dora was good host, answered our requests timely and altogether we had nice stay in Dora Mare. It has good location, 10 minutes from downtown, quiet location and amenities are nearby. We enjoyed view form terrace and solitude of place.
If you go to Ano-Symi, try Tholos restaurant and visit oyher beaches by water Taxi. You will not regret spending money for this.
