Grand Hyatt Seoul is a large hillside hotel on Mount Namsan, above Hannam-dong and close to Itaewon. The current backend custom name is correct. It is the official brand name, easy to search, and short enough to work well in headings and meta fields.
The hotel has one of Seoul's most recognizable view positions. Official Hyatt room information lists 615 guest rooms, including 53 suites, with views toward the Han River, city, or Namsan. This is the reason many guests choose it. The hotel is not in the middle of Myeongdong or Gangnam. It sits above the city, with a resort-like feel that is unusual for Seoul.
That hilltop setting is both strength and trade-off. Guests get space, views, gardens, pools, dining, and a quieter atmosphere than many downtown hotels. They also need taxis or ride services more often than guests staying beside a subway station. Grand Hyatt Seoul is best for travelers who value views, service, dining, wellness, and access to Itaewon, Hannam, Namsan, and the central city by car.
