소현재 (召賢齋, So Hyun Jae) is located in one of the most exclusive areas of Seoul. Members of the royal family and aristocrats lived here during Joseon Dynasty. It retains the city's old appearance, so it has become a popular filming location for movies and TV dramas.
It's in the main street, and you don't have to walk uphill where most traditional houses are located. It's just 10 min walking to the two palaces- Gyeongbok Palace to the west and Changdeok palace to the east.
