The Guest House is very conveniently located just moments from the Seoul Station, which makes it easy to connect to any other lines and get anywhere quickly. The staff here are extremely friendly and will answer any questions you may have.
Breakfast is simple, eggs, toast, jam, peanut butter, coffee, milk or juice, cant complain as most hotels serve this type of breakfast as well.
The common room which is downstairs has 2 really nice computers if you need to check something (also has free wifi if you got your own smart phone / laptop), a huge tv and a few comfy couches to relax. (As of now, the display photo for this guest house is the common room). They also have the option of doing laundry, and the staff will answer questions if you cant figure it out (as it's in Korean, I needed help and was the staff was glad to provide)
The only downside to this stay was the bed. It was not the most comfy one, you can sometimes feel the springs. I dont know if it was just the mattress in my room or all the beds are like this but it wasn't a big issue as one would assume.
If I ever visit Seoul again, I will look into this location again as it was worth it.
