I feel your pain too!! When we lived in an apartment, our upstairs neighbors were a young dating couple. Not much older than us, but we had one young child and a baby. The guy loved to play his music really loud, which didn't bug me so much as the nighttime stuff! They would start getting it on in the middle of the night and I could hear it all!!! The floors were paper thin and I could hear her "voices" and the headboard smacking the wall and so on! It was GROSS!!! I complained to the management so many times, but they said there was nothing they could do?!? I ended up pounding on my celing a few times to get them to knock it off. Talk about a mood killer for them, ha ha ha!! But seriously I don't need to hear that! I don't recall whether we moved out first or if they did. There were many other problems with the complex that I didn't want to be around!
