I've had problems with my (large) upstairs neighbor for the past year. The building repeatedly fined them, the police refused to come out, and I knocked on their door sometimes several times a day for about 9 months straight. My solution was to offer to pay them $$$ for their moving fees and, when they turned that down, I just picked up and moved to another building. That's not really much different.
