You don't need to write letters or call the police..
Just take out those shotguns you've been saving for a rainy day, and practice firing some warning shots. Also, be sure to stand underneath the noisiest room. I'm sure after 5 or 10 mins, when the screaming (or tenants) die down, you will be left with nothing but peace and tranquility. Of course, it would be best if you swung by your local hardware store the next morning for some ceiling repair kits.
