The hostel is nice, near the bus stop, in Jeju it's an important thing if you go around the island with public transportation. The staff was really helpful, they even left their phone for us in lobby and gave an instruction to call a taxi using Apps (Kakao Taxi). 7Eleven and GS25 is just accross the hostel and the road. And if you catch a taxi from Airport, it would only take less than 25 minutes. The room is clean, and the neighbor is quiet too, so you can really have a quality bedtime.
