Dormitories in every university in Korea are similar.

This world is definitely not a bunk bed. Four people are bunk beds.

Conditions are very good, indoor toilets, bathrooms, air conditioning. There is a washing machine on each floor. You can hang that washing machine after washing. The dormitory is really convenient.

But it depends on whether you and Koreans are in the same dormitory. If there is, it will be very inconvenient at first. Koreans are very quiet in the dormitory. I hope you will be quiet, especially if you are a student who has finished military service. If your audio is too loud, Koreans will remind you. Now, when you come to Korea, bring some China trinkets to your roommates, and they will be very happy, even if they are worthless.
