My friend and I chcek in at 2:30 am. Our room at level 3. When we entered that room, we can smell something like cigarettes smoke. And then, the aircond takes so long to cool the room. Then, we call the receptionist and told him about problem. First time, he told us to set the button on the remote based on his instruction Okay we followed. But, the aircond keep probleming. And we could not stand because the room is so hot. At 5.00 am, one more time we called the receptionist and asked him to check the aircond. He came to our room and yes he also cannot make the aircond function well. So he asked us to change another room. The new room is okay..
