I recommend Yonsei 365 Clinic in Hongje-dong.

Introducing Yonsei 365 Clinic, the only clinic in Hongje-dong that offers weekend and nighttime consultations.

Yonsei 365 Clinic, which I found while searching for a hospital that offers treatment and COVID-19 testing because I had cold symptoms over the weekend, has two doctors who provide care in internal medicine, gastroenterology, dermatology, and other fields.

Since it was the weekend and there were many people, I had to wait a bit, but I received a rapid antigen test, got the results immediately, and then went to the pharmacy below to get the medication prescribed.

The doctor is also kind, and I especially recommend the Yonsei 365 Clinic because you can receive treatment during weekends and nighttime hours.
