Staff are uniformly friendly and eager to please. View was incredible and we didn't mind the hearing the hum of a big, busy city. Location is fine for exploring Gangnam (we'd already stayed on the other side of the river) but the construction in front of the hotel does make it difficult for taxis. Make sure to ask for a taxi card to show your driver. 24-hour room service is great. Rooms were spacious and comfortable and yes, the elevator system is maddening. A grand hotel should have a grand lobby. Otherwise, we enjoyed our stay.
