 Staff responded very slow I was assigned to a twin bed room which I requested to be moved to king bed room I was asked to wait in the room I waited for 40 minutes and in the end I went to the concierge To my surprise the staff indeed has done nothing to my request and only made effort to change my room after I approached the concierge One could imagine how long I would wait if I stayed patiently in the rol Facilites are okay not really a 5 star hotel in my opinion 
 Location is very close to historical sites of Vienna
