Clean and comfortable.
Hotel Staffs are standard Korean friendliness (not friendly but not rude).
Hotel is located at downtown Jeju. This means all the necessities are available within walking distance and is nearer to airport (useful for those who has early departure flight).
However, most tourists attractions are at east Jeju, west Jeju and south Jeju (Seogwipo). Driving takes almost an hour to each side of Jeju from downtown Jeju, per way.
Better to stay at Seowipo, just my suggestion.
