I recommend Masan Yangdeok Seoul Children's Hospital.

The Ministry of Health and Welfare operates the Dalbit Children's Hospital system to reduce congestion in emergency rooms and to treat mild cases of children quickly. Yangdeok Seoul Children's Hospital is Masan Dalbit Children's Hospital, and it provides regular treatment until 6 PM on Sundays and public holidays.

It is a very good place where you can use it without being restricted by time. Recently, my nephew was treated for acute cystitis, and even though it was Sunday, he was able to receive medical care and be hospitalized immediately, which was very convenient. The director was also kind, and the nurses were friendly, so we could receive inpatient treatment comfortably.

The facilities are well-equipped, so it was even better.
