You have a right to quiet enjoyment of the premises. You need to make your complaints in writing. The management will get the idea you are about to break your lease if they cannot cure the problem.

You can have a local attorney send the neighbor a cease and desist letter, and a letter to the landlord that he take action. If that does not work, you can sue the neighbor (in small claims court if you do not want to use an attorney) for Nuisance and Interference with the Right to Quiet Enjoyment. If at some point, you want to break your lease, do it with the aid of a local landlord/tenant attorney--never do this on your own. You can also call the non-emergency number of your local police department and ask if your neighbor's actions are a violation of any local ordinances. If they are, call them through the non-emergency number every time your neighbor does this.
