 The layout of the room is a bit quirky you may like it or not The shower cubicle is transparent and is outside the toilet so your roommate will see you while you shower may be a problem for someone travelling with a friend in a twin room for example I tried the restaurant for lunch and I have to say the food was a bit disappointing although service was good 
 Well located not in the centre but a short walk away from Westbanhof underground station also great if you are arriving leaving Vienna by train and there is also a tram stop to go to the centre very quickly Breakfast is nice and there is good choice Free wifi is ok for browising and emailing
