The affordability and location make this an ideal place if all you need is a clean, safe place to sleep, wash, and put your stuff. Staff was friendly, and the amenities were nice (Wi-Fi, a water station, microwave, etc.).
It's fine for one person; however, more than that may be a little much (at least for the room I was in). Also, though there was a small window, it didn't show anything, so if you like natural lighting you'll want to make sure you get a streetview room.
I don't know if this was for all rooms or just the one I stayed in, but the shower room door never closed completely, meaning water running out was a risk when showering. The pipe at the bottom of the sink also wasn't fully sealed, so water would drain out at the bottom. It's fine for Korean bathrooms since there's a drain in the floor, but it may be a little concerning for others if their toothpaste spittle and washed-off handsoap comes back at you.
