I've only had two apartments in my life. First apartment was when I was 18, lived in a section 8 apartment building, neighbor had some sort of mental disability and his wife was completely blind. They would constantly file noise complaints and bang on the walls. My roommate and I were never even that loud, we would watch TV at a reasonable level, and if we started laughing... BANG BANG BANG. Dude would scoff at us when from his balcony when we were walking to and from the apartment, and call us names. He filed his third noise complaint when we had a couple friends over for Thanksgiving. Cops came to the door and were like.. "Uhhh sorry to bother you." On that third one we got evicted, but we didn't fight it because our lease was almost over anyway.
Second apartment I'm 24, neighbors above me are loud as sh*t. I mean raging parties until 3, 4 in the morning. Beer pong, loud bass music. Asked them many times to keep the noise down, but the dude always gets in my face saying he has a "right to do what he wants in his own house." Threw tons of cigarettes off his balcony and blamed it in my girlfriend and I. They finally moved out, but I will never live in a apartment again.
