I got the "deluxe" room because it was the only one available at the time of my booking which had a private bathroom. It was okay, nothing special or terrible.
No Air Conditioning, but this is pretty normal in Vienna.
Unfortunately the bathroom has motion-detector-activated sink and light/fan. I could see why they would want these features in a shared bathroom, but in an en-suite bathroom it becomes a huge and unnecessary annoyance. If you're not moving around in the bathroom (sitting on the toilet or taking a shower), the light and fan will turn off on you -at the exact time when you need them. Also, if you get up to drink water or something in the middle of the night, you can't turn off the light and fan, so you have to deal with them being on for a couple minutes while you're trying to get back to sleep.
