Where does a luxury stay make the most sense?
Gangnam is the strongest fit when premium dining, shopping and business already shape the itinerary. Jamsil suits a more self-contained stay around modern hotels, malls and Lotte attractions, while Myeongdong is easier when this is the first Seoul trip and central sightseeing still matters most.
Seoul Station / Namdaemun becomes more attractive when airport rail and luggage are major concerns. Insadong and nearby Gwanghwamun offer a more cultural version of a premium stay, while Itaewon and the Namsan / Hannam side make more sense when dining and evening atmosphere lead the trip.
