I am a frequent traveler and I have stayed in all kinds of hotels in many parts of the world. This is one of the worst hotels I've ever experienced. Generally hotels in Seoul are nice, clean and cost effective, but NOT this one. Avoid it at all cost, though their competitive price and heavily photoshopped pictures may look tempting.
* Water pressure is not bad, but sometimes hot water would run out in the middle of a shower.
* The building must have been OK (not great for sure) when it was first built, but it was NOT well maintained.
* Towels are so worn out, I had to procure my own hand towel during my stay. I even left hefty tips to have nice bath towels, but I didn't get any. Some towels are not even worthy of wiping floors with. I gave up on getting decent bath towel, and used hand towels after shower.
* Sewer smell kept creeping up into the room. So did cigarette smell from other rooms. Completely disgusting.
* I could hear lots of noise from other rooms. Street noise level was high, as windows were not well insulated.
* Bed sheets were horrible on some days. Many times, it was so rough and worn out, I asked the staff to change the bed sheet in the middle of the night. When the staff brought a new one, it had many holes on it. He brought another one, and when he opened it up, there was a big hair ball in it. Unbelievable.
* Outside line is turned off on the telephone.
* They turned off room temperature control. Either too cold or too hot.
