Welcome to my cozy house,
My house has advantages to travel in Seoul.
First of all, there are several Entertainment companies such as SM, JYP, FNC, etc.
It is close to subway station by foot 5min
Also, you can go to Starfield Coex,Multiplex shopping mall. Furthermore, right next to the Coex, there is a city airport so you can check-in and shop duty-free products.
You don't need to hurry up when you go back to Airport since there is an express bus to ICN Airport very close to my house. 1min.
