Sounds like somewhere I used to live. It was such a shame about the neighbors because otherwise it was a great little apartment, very well located for me.

The neighbor directly above would occasionally commit domestic violence and I would hear some screaming and shouting and banging, and at other times would have loud sex in the wee hours, and at other times have insanely loud parties that lasted all night. Meanwhile, the neighbor below me had a chihuahua who would bark the entire time she was gone. This dog could literally bark for 10 or 12 hours a day without a break.

A very noisy fan next to my bed helped some. These days, a white noise device is probably a better option. Talking to them did nothing. Cops either didn’t give a shit or the girlfriend refused to cooperate with charges or whatever because they also did nothing. Situation never improved until I moved.
