Our room was stiffling hot. We lowered the air conditioning, and nothing. We called tge front desk, they said it took time. We waited and waited and it only went up in temperature. The front desk came at our request and said played with it. Ssme issue. He said the only thing we can do is pit you in another room. Guess what, same thing. We had to open the windows, we could not sleep. Now we had a noisy train passing by every 15 minutes and noise in the street all might. The outside air helped a little but barely. What annoyed us the most was the inconsideration of the front desk, lying to us and making us feel llike we did not know how to use the airconditioning and inconveniencing us at midnight for no purpose. The next morning when checking out, i complained at the front desk. They said at this time in october, the air conditioning is off. So they knew...... This is the worst experience we have ever had in an international chain. This only happened once in a small town in China on a chinese chain, not international 4 star hotel. Really puts the hotel to shame.
