Gung-dong is one of the strongest choices. It sits close to Chungnam National University and KAIST (Korea Advanced Institute of Science & Technology) and has a large student and international population, with restaurants, cafés and relatively affordable small-unit housing.
Pros Affordable student housing Close to universities Lots of restaurants and cafés International atmosphere
Cons Can be noisy and busy Smaller rooms and older buildings are common.
Eoeun-dong is at the KAIST area and has shops, restaurants and everyday services. KAIST itself lists Eoeun-dong as an area with restaurants and shopping close to its West Gate.
