Jeju have two different region New jeju and Old jeju.
where I live is in Old jeju, so not quite City-like region, but still a city.
My place is close to city hall, very much have essential facilities; Super market, Convenience Store, Movie Theater, Bank, etc.
In front, there is a Shinsan-Park so i can take a walk around and feel the wide sky and smell greens. I can live relaxed in Old jeju.
