what I like: very convenient location and very well equipped hotel, good value for money
It is only 1-2 minutes walk from Chungmuro station exit number 7 if you accept walking stairs. If you don't take the stairs, you have to walk a few more minutes.
I got free upgraded to a twin bedroom which I am really grateful. There is toothbrush, toothpaste, towel, water dispenser, microwave, sink, washing machine etc in the common area.
I enjoyed some noodles and chicken soup in restaurants nearby and they are really good (and maybe a bit cheaper than those in the tourist spots)
You can walk 15-20 minutes to Myeongdong.
what I don't like: basically nothing, the only thing is that in night sometimes you will hear the sound of your neighbour but it is really minor to me.
