Hi
I had a couple of experiences that related to this area, before the apartments opened it was a very quiet road, I know when somehwere new opens there can be lots of parties, but the noise every weekend, some very anti-social behaviour, hopefully it will settle down in time, but I know people who bought apartments in city west and belfry and did not have the same kind of problems, it could be that these apartments are in very close proximity to the houses and each other, they may not be spaced out enough.
Hope this helps, wish you luck in your search.
