All sounds familiar with the Apartment lottery. I remember I did complain to the management about the yoke next door and things might improve for a while then kick off sporadically- to put it in context she was defo on drugs, had worked as a prostitute and drink was a constant theme obviously. Also had a little kid who the social services had been on about.
With that kind of messed up living I think there’s little enough they could do (I know eviction was threatened but these types are well up on their so called “rights”).
In the end I gave up caring as I was moving out anyhow and buying a house. Would be very reluctant to buy an apartment again unless it was in an exclusive mature building. As I say after it’s a lottery as to what riff raff are around you.
