Vey pleasant stay! I arrived around 2AM (late flight from Manila) and had to wake the Ahjussi which was sleeping in the lobby. Sorry, Ahjussi. I indicated I will be arriving at 11:30PM but due to the long lines in the airport, I arrived later than the noted time of arrival. Thankfully, there is an elevator. Just had to proceed to 3rd floor. Smooth check-in, he just asked for my name and did not look for my ID or passport. He immediately showed me the room and provided the key card. I stayed at the Basic Single Room (3rd floor). There is no private bathroom/shower but I never really had to wait for the shared bathroom. Note that there is no bidet and no trashcan in the bathroom, so I had to throw my trash in my room. I think they just forgot to put one at the time. There are 4 pieces small towels in the room, a small mirror, tissue, AC and blower. The bed is very comfy, I slept well. Also, there is a balcony. Breakfast is bread, jam, coffee and tea. It is provided from 8:30 to 9:30AM (self-service). I haven’t tried the bread and jam. There is a coffee machine that serves espresso and americano. I liked their coffee. :) The place is also very close to Unseo Station. Less than 10-minute walk. Just ask Ahjussi how to get there. You will have to pass by an underpass.
