Great hotel for the price you pay. I was very happy overall with my stay.
My one complaint might seem like a small one, but would be so easy to fix: please allow guests to use the HDMI input on your tv:s. You have a big television in the room with an HDMI input which has been disabled. This was common 5 years ago, but most hotels I have stayed in recent years no longer disable these connections. There are several reasons this is annoying. One is that when most of the tv content is in German, it would be nice to watch content of my own choice on my laptop. Second, and in this case more importantly, on a business trip it is good to be able to test and practice your powerpoint presentations on a big screen.
But as I said, otherwise a very good hotel for the price.
