Having a noisy neighbor can be a stressful and difficult situation to handle, and that noise can turn an otherwise great apartment into a bad one. Here are a few tips for dealing with a noisy neighbor.
Contact your manager: the first step is to contact your manager and let them try to fix the situation. Be sure to keep notes and document the times when your neighbors are being loud.
Respond with a polite note: if the situation continues, write a polite note explaining when and how they were being loud. This personal response could be enough to stop the behavior in its tracks.
Get proactive: if a shared wall is the issue, try decorating with fabric, cork or any other sound proofing materials.
