 room was very hot and when complain about it they moved us to another room but still the other was hot too when we asked the staff about the AC issues the answer wasn t convince as the AC is working cool but since we are from middle east the temperature is different hence the Ac cooling is different than the middle east Strange answer giving the fact that we were on Europe road trip and before Vienna we were in Budapest and didn t face the AC issue 
 hotel was clean and quite
