Stefanie · CoupleGRGreece "Hello, we booked online and paid via PayPal; everything was handled extremely professionally. We were given private parking, comprehensive information, and professional instruction on the boat. We'll never forget this day. It was wonderful. Since we had no boating experience, the nine hours on the water were a fantastic experience! We were also helped again with parking in the harbor. We felt well looked after and would definitely recommend them. Thank you so much 🙏, see you next time! 👍👍👍 Five stars 🤩"
