The hotel is great, but insanely expensive breakfasts, we refused. There is nowhere to sit in the lobby on the 1st floor. You can't smoke anywhere, not on the street either.
The most expensive and luxurious hotel in Seoul with a wonderful view and location. There is everything you need for a wonderful holiday near the hotel! So if the means and opportunities allow, then I highly recommend it. The hotel has wonderful service and staff who speak different foreign languages!
