I live in a block of 6 flats (housing association). I’m on the first floor, which means I have a neighbour above and a neighbour below. Flat upstairs is a bought flat, rest of us rent through the HA.
Neighbour upstairs is lovely. Talks very loud for such a dainty person, so I can always hear when she’s on the phone, but essentially is a lovely lady, similar age to me (40’s) and a good, considerate neighbour.
Every neighbour I’ve ever had below me in the 23.5 years I’ve been here, has been awful.
First I had the noisy sex neighbours. I heard all their moans a groans
. Although when they argued it could be quite comical. During one of their rows, I once heard the woman shout “Fuck off Steve I’m on the toilet!” 
Then we had noisy barking dog man. Nice guy really, but kept leaving the dog alone and the poor thing would bark and whimper for hours on end.
Then we had noisy music man. Who liked playing his stereo full blast. After beating the crap out of his door in sheer frustration early one Sunday morning in nothing but a dressing gown, I eventually got my own back by putting my speaker on the floor and blasting Smack My Bitch Up through his ceiling. He stopped after that and thankfully moved out shortly after.
Then we had dodgy dealings couple. Who were constantly throwing late night mid week parties and having the police turn up for whatever reason. One night they were involved in some kerfuffle with another annoying neighbour upstairs and I opened my front door to find a young black guy standing outside my door like a rabbit in headlights, wearing a balaclava and a hat and holding a hammer 
Then we finally had a little ratbag that moved in and made everyone’s life a living hell with her constant racket. People turning up at all hours, entering through windows. smoking weed, loud music, shouting and swearing. She eventually had a child, which she constantly screamed all kinds of profanities at. And culminated in her calling me a black c**t (I’m mixed race) when I yet again asked her to keep it down. Thankfully she moved out last year and nobody has moved in and it’s been BLISS.
We had some issues with one other flat opposite my neighbour on the top floor with a couple of nightmare neighbours that lived there over the years, but thankfully a lovely lady has moved in now.
People ask me why I don’t rent privately. Thing is the HA rent is cheaper (£388 pcm), but the main reason is that I have an assured tenancy - meaning as long as I pay my rent I have a home for life. Unlike private rental where you can be turfed out at any time. So that’s the only reason I’ve put up with it for so long!
