Lotte Hotel Seoul, in a gleaming high-rise perfectly positioned near City Hall, about midway between Deoksugung Palace and the Myeongdong Cathedral, was the largest luxury hotel in Asia when it opened in the late 1970s; thanks to ongoing renovations and additions, it’s kept up with the times. Rooms and suites are every bit as refined as you’d expect of a five-star business hotel, with state-of-the-art technological features, luxe he:on beds, and sweeping views over the city below.
