 No air conditioning in the rooms There is just an old noisy fan and with 30 degrees outside makes it difficult to sleep Vienna is always hot during the summer so you would assume that a 4 star hotel would have air conditioning in the rooms especially since the price per night is not peanuts Top that up with the staff shouting down the hall ways at 7am 
 Location was perfect right in the centre of vienna The rooms were nice and big comfy and also clean Breakfast was also good and wifi worked really well everywhere Tv also had some good channels to watch for non speaking Germans
