Nanjang Guesthouse is a guesthouse in Jeju that operates in a renovated old house in Ildo 1-dong, Jeju City, close to the airport and E-Mart. It has a music bar and lounge on the first floor and a rooftop space, and music and parties continue there until late. Rooms have no keys, and the bathroom is a shared facility without a proper shower booth. Soundproofing is weak, so the sound of doors opening and slippers dragging echoes clearly inside the rooms.
