It was good
Pros: I didn't want to be disturbed throughout the stay, and I wasn't, so it was good. I could go out and come back at any time, which allowed me to visit Berlin, while having a place to return to and relax in front of my PC. There was a small fridge for drinks. I didn't need it, but it was there so it was good anyway. I don't think I'm the type of person who usually stays in these kinds of places, but it was good so I will return when I come back to Germany. Cons: I couldn't connect my devices via HDMI to the TV. That being said, it's really not a big deal. The rest was good.
