Myeongdong Skypark Hotel.
However, is clean and new.
Some rooms come with bathtubs.
When I was there, they had a tie up with etude house so there was a small segment for diy manicure and a free mask
Location wise is good as it is at myeongdong. Just walk out of the hotel and you are at myeongdong shopping area.
Ten minutes walk to namdaemun and 15 mins cab ride to dongdaemun. 3 minutes walk to the subway.
