Seongbuk (Jeongneung) Must Stay - Wave - Seoul Hotel

Group travelers often note the warm bathroom floor heating and dark room from windows making it easy to sleep. The owner's kindness and nearby convenience are commonly praised. Some say it's clean and comfortable when non-smoking is well-managed.

However, poor soundproofing lets in neighbor noise, elevator sounds, and karaoke from below, as per multiple reviews. Cigarette smells, bed stains, and hair are serious hygiene complaints in some. Weak shower pressure and auto-off bathroom lights are also issues.

It's okay for groups just needing a place to crash or less hygiene-sensitive travelers, but couples or cleanliness-focused ones might want to avoid it.
