I made a reservation because the rating near Seongsan was good and the convenience seemed good, but the room was definitely too small for two people. It wouldn't be bad for people who just sleep or don't care much, but for those who feel uncomfortable in a small space or who value time at the accommodation. I think you should definitely get a larger room. I also didn't like the fact that the interior of the room was exposed concrete. The same goes for the floor.
Unless you are a solo traveler and want to wash up as soon as you arrive and take a good nap, the room feels very cramped and hard. Breakfast also included bagels and coffee, so I don't know if you don't like bread. I guess it's because I'm older, haha.
