 Nothing
 We booked two rooms for two nights The rooms were spacious and clean the mattress and pillows were soft and comfortable We had requested for early check in prior to coming to Vienna which we got The air con was fine The bathroom was clean with a good sized shower The hotel was 4 mins walk to the nearest train station Lots of good restaurants near the hotel Also there was a hotel nearby where you could do your own laundry which we availed The breakfast was included in the room charge and they had a very good variety of food All in all avery good place to stay Will recommend it to anyone who wants to visit Vienna
