The location is near Hongik University subway station (10-15 minutes walk), convenient to and from Airport, and go around the city through Subway.
A little bit noisy during nights as there are some restaurants and bar around, it is good for some people though.
The room is tidy, clear and well managed, the auto drinking water machine is a plus (i.e. can get Hot, room temperature, cold water instantly)
The Guest house lady is very nice, took care all our request promptly.
Overall, a good place to stay in Seoul especially for family.
