Hello everyone! I will be travelling to Seoul for the first time this coming December. I got a free KAL limousine bus ticket. The KAL limousine will stop at CITY HALL LINE 1, NAMSAN LINE 2, GANGNAM LINE 3A, GANGNAM LINE 3B, JAMSIL LINE 4. I was wondering which of this stops shall I take to get to DOULOS HOTEL? Can anyone please give me information as to direction and how long shall I walk to get to hotel? Thanks!
