I'm in the middle of a council estate, my place is actually HA. When I first moved in I had problems with one neighbour who decided I didn't need a bungalow as I was 'too young' she also accused me of being, "educated" apparently that is a fault.
I have had problems with noise in the summer and the council has dealt with it, the only problem being that the council office is closed at the weekend when the parties were happening. I did suggest the department have someone 'on call' but apparently that can't be done.
But most of my neighbours are fine, lovely people.
Lots of people have lived their whole lives on the estate. My next door neighbour to my right was brought up on the road that backs on to us, the lady opposite is one of the 'Windrush' generation with numerous family members who visit her daily and might come over to mine to stroke the cat.
Round the corner is a community centre where I did some shopping yesterday in the 'community shop', they had opened a 'sweet shop' in the garden and the garden was full of children with painted faces. There will be events all of the Easter week day holidays.
They also run a café, a warm space, cooking classes and have children's dance class one evening.
I would say take the flat and seek out the good people around. Take your toddler to the local toddler group, use the local shops, local whatever there is, it would be a library, community centre, park or what ever.
I honestly believe there are more good people than bad in the world and you get a mix everywhere,
