Best hotel stay...ever! My family and I loved it at the Sofitel Ambassador Seoul. They have a great breakfast buffet, and the service was impeccable. The only small suggestion I would have is to direct guests to the other elevators that go to the lobby; there was often a wait for the 2 elevators to the lobby from the concierge area. Luckily, we found the other bank of elevators on the first night. The hotel is right next to the Lotte mall which was convenient as we packed lightly and bought a couple of outfits while in Seoul. And Sokchon Lake across the street was a beautiful sight, especially during our stay when the cherry blossoms bloomed. All in all, a great hotel which we would be happy to stay at again.
