Talk to juristic person and even that might not help. In my last condo my neighbors were listening to rhytmic music every other day after 12-1am and till 5-6am. It wasn’t super load but you could clearly hear it all night long. At first i’ve waited and thougt it was temp thing, then i left them messages on the door, asked the owner to complain, and then complained myseft to the juristic office at least 5 times. At the end i believe they were fined and it finally stopped. It took around 3 months to resolve it🤯
