Spent four days in Seoul on our own, on the last day our flight was at 9 pm, so we wanted to have a private car and tour outside the city until we had to leave. Found Yoonsik ("Stefano") and wrote that we were interested in the DMZ and then left the rest to him to devise. Did not disappoint, after DMZ he drove us to Ganghwa Island; many sights including Dolmen Stones, fortresses and a beautiful temple complex. Great local lunch with loads of banchan. Dropped us at Incheon Airport at the end of the day. Stefano was bright, good conversationalist, knew a lot of history, very personable. Plus wonderful large touring car. High recommendation for Yoonsik H.
