You thought Korean hotels were any better than Chinese one? Me too. It's wrong.
So a few months ago, Chinese luxury hotels were caught using the same toilet brush to clean cups as well. Now Korean hotels were caught, too . Again, luxury hotels in Seoul. Their average daily rates are easily over $200. At least Chinese hotels were in Harbin, where Kempinski (one of the caught hotel) cost about $77 on random date in March. On the same date, "S" hotel costs $250. So it's not about the price you pay. Even if you pay over $200 in Seoul you'll still end up drinking water from sewage cup. Purely disgusting.
