 The air conditioner did not work it was too hot it was just blowing air This is a 4 star hotel and the fact that my room was burning hot is no excuse the staff were too kind they changed my room but still same story I am sure the central system had a problem or was not switched on to cut cost 
 This hotel has the nicest staff of any I have been to in Vienna The staff of so kind to the point that you feel bad for complaining I would like to thank the front dear people for doing their best to help us
