I stayed here while it was under renovation, so it wasn't very comfortable. The outside area was dirty and a bit scary because I passed a room that was being renovated. In fact, I bumped into a construction iron while checking out...
But it seems like once it's tidied up, it would be great for backpackers. The room is quite adequate (for a single room), the air conditioning is cool, it's close to Kiaracondong station, and there's a minimarket and restaurant nearby. The downsides are the lack of a bath mat, no hangers in the bathroom, the sheets looked worn, although they didn't smell, but they didn't smell good either. Unfortunately, you could hear the noise outside, and the door also had a mat and was difficult to close, making it noisy.
Overall, it's still okay for a quick stopover.
