Booked in for 7 nights in January, 2020. Location of the hotel is just 50 meters from Exit No 9 of the subway. However, you do have to remember the walk from the train platform to the exit is several hundred meters. On the other hand, Namaemun Market, MyeongDong, Seoul Station are all within 10 minutes walk from the hotel. Gyeongbokgung is only 30 minutes away if you are willing to walk (There is a public light bus that will take you there as well.). If you travel to and from the airport using one of the airport buses, the bus stop is just a hundred meter away.
The room that we got has a double bed, a single bed and a sofa on the side. It is around 30 sq. meters and it is really roomy. Big bathroom/toilet. Free Wifi works well. Not much street noise at all. Hotel itself is quite new and well maintained.
Not a bad place to stay for a couple of days!
