The hostel was okay, but the reasons I decided to move to another hostel were: toiletries were watered down, guest towel cabinets were empty, no electric outlet at my bed (not any extension cord). Apart from that the room and bed were pretty clean, and other travelers were friendly and easy to talk to! This hostel has a communal area to hang out, making it easy to make new friends.
The train station is one minute from the hostel, and it’s really easy to get to anywhere around Seoul.
