I recommend Yonsei ENT Clinic in Suyu-dong, Gangbuk-gu.

The hospital I'd like to introduce is Yonsei ENT Clinic, located in Suyu-dong, Gangbuk-gu. It's easily accessible and offers quick and friendly treatment, making it a popular hospital in the neighborhood. I recently suffered from a cold and was almost completely cured, but then suddenly developed otitis media, so I decided to visit. Even though it was my first visit, I felt completely comfortable and received treatment. I took my medication regularly, and things improved significantly. However, because the hospital offers excellent care, there's always a long wait. It tends to get crowded during lunch hours and on weekends, so it's best to arrive at least an hour before closing time to register. This hospital is also unique in that it offers Sunday services, from 9:00 AM to 4:00 PM, with an hour-long lunch break. It can be daunting to go to the hospital on a holiday, but having a nearby clinic open on both Saturdays and Sundays is reassuring. If you live nearby and need treatment for a cold or ENT issue, I highly recommend stopping by.
