I live in a one bedroom upstairs flat, there is just me and one flat underneath and there is a shared driveway for both flats. The downstairs neighbours have three small children in their flat, I have lived here for three years and it hasn’t previously been a problem as children were only baby’s. Recently they have been letting them out to play on the shared driveway and they are riding scooters/bikes round and round my car in a very small space ( never round their parents car funnily enough) and I am worried about my car getting scratched. They are also leaving bikes in the middle of the driveway so I have to get out and move them before I can get on the drive. They are still out now at almost 8pm and parents are inside no supervising them at all and they are squealing/shouting which doesn’t bother me as much but I am starting to get a bit irritated and I am close to saying something. There is a shared courtyard round the side of the house that they could use to ride bikes.
