Asian Side 4 Stars Hotels

"I had surgery and specifically requested a non smoking room prior to check in. Upon arriving to my room, it smelt like cigarette - so the front desk accommodated a room change. The second room also smelt heavily of smoke, and upon requesting for the third time a non-smoking room, I was told the best they can do is to “spray the carpet”. Due to complications second hand smoke can have on bleeding and other surgical risks, I couldn’t even stay my first night. I had to check out within a few hours and the hotel is refusing to provide a refund, even though it was for legitimate medical reasons. They are saying I “refused” a room change, however, it would’ve been my third time changing rooms. At that point is what made clear, no matter which room they put me in, it’s simply not a smoke free hotel, and a “non smoking room” was wrongfully advertised. I am now out $400 and they refuse to refund me. "
