 Heat controls in the room were a bit erratic in the living room it would get really cold at times even though the temperature was set to 25C in the bedroom we woke up in the morning with a sauna like temperature It was indeed very challenging to get the car in and out of the private parking without any scratch If needed ask for assistance from a friend or even from a staff member 
 Very friendly and helpful staff Room was neat and clean modern looking very pleasant Breakfast was buffet style and had everything I needed to start the day Location was perfect a 10 minutes walk from Hofburg through Mariahilferstrasse
