Jesus Christ, my neighbours upstairs are loud and noisy. So much that the neighbours one floor below me can actually hear them as well. And they're not exactly well behaved either, as you can hear from the language they use. Also, this building isolates the sounds pretty well, but these people are noisy as hell. Oh, and it doesn't stop at just them shouting and their children screaming, because every once in a while you can hear a thumping noise of some kind. As a matter of fact, I could hear one of their children running as I was writing this.
They allegedly lived in a village in the most desolated part of Croatia before moving in upstairs from us. To make things worse, my mum did complain to them before, two or three times if I'm not mistaken, and that didn't help much, if at all.
The flat they live in is owned by someone who keeps renting the place to the worst possible kinds of people. It's always some sort of problematic people living above us, but even if they were all bad behaved and pretty loud, none were as loud as these people. I seriously don't know how can this family be so loud, it's as if they're constantly in a row, and keep moving their furniture every day on top of that. It's not that they had low benchmarks to beat, as there was a bunch of soldiers who'd get drunk on a regular basis upstairs amongst the others.
