"Good points:
The location is excellent. The bus stop for Incheon Airport is right nearby. There were also many restaurants open late, so I could enjoy a meal even after a late concert. The common areas were kept clean, and the cold water provided was a lifesaver. The refrigerator and microwave were also clean. The other guests were very quiet, and I wasn't bothered by outside noise. Having a trash can in the room was convenient, so I didn't have to climb down from the top bunk just to throw things away.
Bad points:
Towels were placed on the top shelf of the locker, and water, earplugs, and slippers were on the bottom. However, the bottom shelf was designated for shoes, so I was uncomfortable with those items being placed directly in that space. The shower booth was very small. There was no bath mat, so the floor was soaking wet, and the wetness spread to the toilet area. On Saturday night, many people used the facilities, so there was a lot of hair on the floor, and the trash cans were overflowing.
I requested a bottom bunk but was assigned a top bunk. The stairs were steep, which I found difficult, and someone on the bottom bunk had hung their clothes, making it even harder to climb.
When I closed the bed curtain, the air conditioning couldn't reach, so it got very hot while I was sleeping.
There was a lockable storage space next to the bed, but it contained opened feminine hygiene products, so I didn't use that space.
On my second day, when I returned to the hotel, my locker had inexplicably reset to 0000 instead of my set combination.
There were instructions in Japanese in the room, and the staff were very pleasant. The check-in terminal also had a Japanese option, making it easy to use."
