I recommend Hongje-dong Yonsei 365 Clinic.

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

I had a cold over the weekend, so I was looking for a hospital that would test me for COVID-19. I found Yonsei 365 Clinic, where two doctors treat patients in internal medicine, gastroenterology, dermatology, and other departments.

It was the weekend so there were a lot of people so I had to wait a bit, but I got a rapid antigen test, heard the results right away, and got a prescription from the pharmacy downstairs and came back.

I recommend Yonsei 365 Hospital because the doctors are friendly and you can receive treatment especially on weekends and at night.
