hello i want to stay for 6 days during a congress and its important to get enough rest, so I wonder if there is a police for the stay like if the light is turned off at a certain time other rules to keep it quiet during sleeping hours?

They do have rules but it remains a bit noisy through the night since it is for all practical phrposes a hostel. Great location though.

There's always a choice of the type of accommodation you require. If you book early enough, you might get a single person room. I stayed in a 4 person's room and did not experience any type of noisiness. It was, however an overall great experience.

We stayed in a traditional room and did not experience any issues with noise.
