What to do in the event of nuisance/noise caused by third parties?

Our initial advice is to approach the person causing the nuisance, explain to them in a friendly manner that their behaviour is bothering you and ask them to stop. It may be that the person causing the nuisance has no idea of the impact their behaviour is having. If this fails to yield results (after repeated attempts), you can turn to the police or municipality. You can report this to the landlord/manager but they have no influence over nuisance caused by third parties.
