What I've found is that people who aren't being respectful are rarely the kind of people to curb their behaviour after a nice chat. I had a neighbour that would incessantly play loud music (in a building where noise was prohibited in the lease), and I politely explained that it was easily heard and disruptive, and asked if they'd please turn it down or use headphones. They said sorry and agreed to, but then didn't make any changes. Next time I knocked they didn't come to the door, and another day I heard them yelling about how they choked some guy out and wanted to kill them - so all my future complaints just went to the landlord till eventually the tenant was evicted for harbouring a criminal. With that said, I still agree that it's worth just talking to them as the first action, in case they are just a nice normal person who doesn't realize how poor the soundproofing is.
