Good location, 1min walking to exit 3 of dongdaemun line1, which is just stairs.If need to take escalator, can just use another exit which is just a few minutes walking from the hotel.
15mins walking to Gwangjang market, and a lot of restaurants and shops on the way.
During my stay in the hotel, I went back to the hotel at 12am and even after 1am, no problem for me at all cuz it is just beside the main road and a 10meter alley to the hotel.
Room is clean, water pressure is fine for me as well cuz I am using the rainbath. No separation of bathroom and toilet, but the water won't splash into the room if the door is closed properly. Hot water and microwave available at floor one. A good hotel to stay if you are solo traveller.
Will revisit if I am back to Dongdaemun to stay.
