 Aircon did not work 24oC all night instead of 18oC way hotter then outside Windows do open but we were on 1st floor overlooking a main road so very loud and smelled bad I specially asked three times not to have the night manager visit because my son was ill and had finally got to sleep but still they knocked to come in on two occasions after I rang asking for advice on whether there was a way to check or reset the aircon and where the instructions were 
No Positive
