I booked a non-smoking room. When I entered the room, it didn't smell. But at night, around 7 o'clock and above, cigarette smoke came from nowhere. It smelled so bad that I couldn't breathe. The AC was turned off, but it still smelled. In the hallway to the room, I smelled something and the smell of cigarettes. It was very noisy, the knocking sound from other rooms and from outside was very disturbing. As a result, I couldn't sleep last night because of the cigarette smoke and the noise. Rather than endure it, it was better for me to move hotels. I complained to the receptionist about the noise, and their response was to reprimand me for another room. Regarding the cigarette smoke problem, our response was that it was no smoking. But in fact, the room still smelled of cigarettes and was noisy repeatedly. Non-stop.
