Are you American? I ask because I’ve been told in a lot of other places it’s abnormal to have paper thin walls without sound insulation, where you can hear every fart a neighbor makes. I’ve only ever rented in paper-walled shitholes in the US, so I couldn’t say. Either way, it pisses me off even more that this is a solvable problem that landlords have simply chosen to not solve, because it’s cheaper and they don’t have to live with the literal health consequences of constant noise pollution.
