Alzrius, I think we live in the same city. In fact, I once spent a year living in a rented house near a major University campus on a street filled mostly with other rented houses, so I think I know the general neighborhood you're talking about firsthand.
Our house was generally pretty quiet, we weren't loud party sorts, but our next door neighbors were. They would get loud and drunk, and sometimes park their car in the wrong place, or play loud music at night. They weren't very pleasant neighbors to say the least.
So, the most sociable and party-oriented of the housemates decided to take on the role of being a diplomat. He went over and got to know them, share a few beers, give a human face to their neighbors, and let them know that their neighbors didn't care much for the very loud music and wild parties at 3 AM. It took a bit of adjustment, but we did get them to significantly curb their behavior and clean up after themselves more, and we accomplished it without too many hard feelings.
I know you said that you weren't interested in reconcillation, but for next years crop of college students you might want to consider a Diplomacy check instead of an Intimidate check, it can work and be a lot less drama and confrontation filled.
If Diplomacy fails, then go with the cameras, documenting everything, police, et al. I believe the city we live in has a noise ordinance with some teeth to it passed a few years ago specifically designed to target loud parties in these circumstances.
