 There was a general WiFi outage which took 30hours to be fixed Totally unacceptable We had to use roaming data on the smartphones for which the Hotel did not offer any compensation 
 The location is perfect if you are attending a conference at the Vienna Conference Centre It s 5 minute by walk Getting to the city center is also easy with the subway 2min walk Rooms are spacious and comfortable Overall good experience and the hotel s restaurant is good
