Theravada temple in Seoul

Hello Friends.
Sorry again for such a question, but many things have happened since I asked it for the last time. On the 21st I am moving to Seoul, Korea and most probably will stay there either two month, or perhaps many years - who may really know? Life is so unpredictable. Could anybody please point out for me a Theravada temple there, a quiet one, where I can just go and sit/meditate quietly. I will be living in Yongsan for the first two months and then may be will move closer to Seoul National University.
I am really sorry for asking the same question, now for Seoul, but please help.
