Actually, my current ones aren't annoying at all. I mean sure, sometimes the hallway smells like cigarette smoke too much (someone's smoking in their apartment), sometimes dogs bark a bit too much, there are sounds of renovation etc. but never to the point that it would really bother me a lot. My neighbors aren't nosy either or anything; my interraction with them is pretty much limited to saying hello and such on the yard or the lobby if I happen to run in to them.
Sometimes I wonder if I'm the annoying neighbor in this building, listening to music too loudly or something, but I suppose not since I've lived here for almost four years and haven't gotten any complaints.
