This hostel is rather modern and new. The location is amazing for all the activities around Sinchon, Yeonnam-dong and Hongdae as well as other areas, as the bus stop is really close by, with many buses. there is a bit of a hill to get to the hostel along the roads, but I found after arriving that there is a nice staircase/ramp from the main road directly to the hostel. It comes out right in front of the hostel.
My only (and significant)complaint is that I booked a deluxe double room to be by myself. But when I got there, the double rooms are actually two rooms (each with their own door obviously) that share a common entryway. Not usually a problem, but the door to each room was not able to be locked AT ALL. there was a flimsy latch and hook, and not even a door handle, so the door was always slightly open. I did not feel comfortable staying in the room as I didn't know who was staying in the other room, and they had 24 hour access to myself and my belongings. Not what you expect when you fork out the extra money to have a room to yourself. I expect privacy and security. (Note the door to the common entryway was secure, with an electronic keypad).
in the room you also heard all the plumbing and other noises, as the plumbing is not hidden or insulated in a roof cavity, but the room follows an industrial style of exposed plumbing.
Also, I stayed during winter and the room had a portable radiator to heat the room. It did get the room warm enough but i didnt like that.
