10/10
I stayed here 13 nights.
The staff is very nice !
Even if the owner doesn't speak english, he always does his best to help us!
If your height is higher than 1m85 ask for a room where the bed isn't stuck between 2 walls.
I didn't sleep a lot, but I wasn't here to sleep, plus you've got some big noise from the cars outside.
And the curtain is very light, so the sun can pass trough. (i think, it's the same in every guesthouse in korea)
It's well located, so you can do some shopping in the malls around.
