We've got the same problem. Noisy people downstairs. They always have a party on saterday nights. they start out at about 8:30 and to till about 10 or 10:30, then they all leave (to the bar I guess) and come back sometime between 2 and 4 am and wake us up. They go till 6 am. I can sleep through it usually, but my wife is a light sleeper. We have complained twice to management, both times she said she'd send a noise complaint letter. I cant believe that we are the only ones complaining, there are units attached on both sides and behind, and us above. On 3 separate occasions we've also gone down to tell them to shut-up. Sometimes it works, other times it doesn't. This past saterday at about 5:45 my wife woke up, i slept through it, but apparently she heard yelling and fighting between male and female, and them a thump and female starting crying yelling "why did you do that" and left, slamming doors. Wife thought the guy hit her, (wouldn't suprise me). If I would have heard it I would of called the cops right away! We havn't called the cops to make a noise complaint yet, but next time it wakes me up I will. My wife won't cause she's a pussy when it comes to stuff like that. Had to call about a car alarm going off all night acouple weeks ago.... think I posted about that.
