How to stay in korea for a long time with a low price.

I think 'Gositel' is one of cheaper way to stay in the city of korea.
It's really small as you see.
This is what I decided to stay for a month.
It depends on the type though, it has shower booth as well.
I wanted toilet in it but public toilet only in this 'Gositel'

Yes i know that it looks like a jail.
If you have enough money then you can use nice hotel without hesitate.
But if you have not enough money then it will be good choice.

Guess what!
290$! In a month.
What a price!

And free rice free kimch even ramyeon too!

Anyway, i have to be here at least for a month.
