This is a property that checks all the boxes. It is steps away from the subway, regular bus stop, and airport bus stop. Plenty of options for currency exchange (in the lobby and along the street nearby). Plenty of shopping and dining options nearby. The staff are friendly and very efficient. The interior is beautiful; the rooms are clean. We were upgraded to a deluxe twin double during our stay and had an amazing view of Namsan Tower outside our window. Definitely recommend this hotel.
