Here is very reasonable price and comfortable enough.
The best thing is location. Gongdeok station has many subway lines.
Subway station takes 5mins from this recidency.
There are Airport train Line,line 1&5 and 6.
If you'll love having your own private space.
Highly recommend for the budget traveller!
Please, check this out before you make reservation.Think about price ;) If you stay here you need to share kitchen, shower booth and restroom. Those are not great condition. remember these!!
