The first room provided on first floor was labelled non smoking but when lift door opens, you could immediately smell cigarette even at the corridor. Room was worse.
Credit to the receptionist, room change was done swiftly.
However, the room and toilet is not clean - dusty floor, unclean towel, smelly bed sheets, smelly pillows, stained toilet wall and shower glass, the shampoo and shower cream smells weird (and bad).
There are much better hotels in KT to choose from so I will never return to this one.
