I live on the top floor of a two story apartment. We're in lease until December. The people in the apartment below us are college students and they have parties aaaaaalllll the time--like every night. And I'm pretty sure they have orgies, too (seriously) because I have to park in front of their living room window and they always leave their blinds open and there will be like 5 or 6 people in the living room with just their underwear on and playing like, "bow chica wow wow" music....

Anyway, my husband and I have both gone downstairs several times and politely asked them to be a little quieter. I'm not an idiot. I understand that hearing other peoples' noise is a downside to renting an apartment, but they are waaay too loud. I never hear the other neighbors and the people below us said they don't ever hear us (annoyingly enough, not even when we're banging on the floor).

Told the landlord. She printed out a neighborhood flyer "being considerate to neighbors". It did no good. What now?

And they're really sweet people by the way. They're usually pretty apologetic if we tell them they're being loud. One of the girls always makes small talk if we pass outside or something. I don't want them to hate us. But I can't take staying up till after 1 am every night not being able to sleep because they want to have a drunken time.
