 Being forced by the hotel to use booking com I specifically asked not be send any adds and guess what 5 minutes after I booked the hotel and I had to give my email address although it was not need for anything booking com send me more adds which means that they used my email address to their benefit against my specific request Will not use any hotel in the future that uses booking com Also I asked for a quiet room What I got was a room to the back with very very loud air conditioning the whole night and then since 5 or 6am sounds of staff using garbage bins or some other bins and closing it loudly and thus waking us up 
 It would be nice to have tea or coffee in the room most of the hotels have the tea and coffee tray and they also have water bottles The hotel could use regular tap water as water in Vienna is considered very good and thus they would not need to use any plastic bottles just refill a glass bottle every day Tasty breakfast in a beautiful room
