Park Hyatt Seoul sits across from Samseong Station and COEX, with rooms looking down over Samseong Station and Teheran-ro. Guests can use the Cornerstone lunch and breakfast service along with the food and beverage service at the hotel restaurant. The lobby is on the 24th floor, so moving to a room or any other floor means passing through the 24th floor. Construction at the Samseong Station intersection and nearby billboards make the rooms noisy day and night, and the rooms stay bright at night as well.
