 We had a suite and one of the radiators in the lounge did not heat up hence the room in which my daughter was sleeping was not warm I spoke to the receptionist about this and was initially given a fan heater with a promise that the fault would be remedied The following morning I had a further conversation with reception staff but still nothing was done A black mark against what was otherwise a very good hotel 
 This clean well appointed modern hotel is situated 100m from Wien Westbahnhof so access to the U bahn is very convenient Good selection of restaurants in local area and the hotel room was quiet
