The flat is really good located. Step outside the door and you are directly in the old city with all the bars. On the one hand, you have really less time wasting when visiting the old city and enjoying the night life. On the other hand, it could be at the weekend a little bit louder. We decided for using the night, thus we didn't have any problems.
The apartment itself was like expected and described by the photos. The handing over of the keys was very easily and we just left them when leaving the apartment.
