I've lived in a variety of multi-family units, some have _definitely_ been far too noisy. I'm still trying to work out what some upstairs neighbors I had a few years ago were up to regularly that sounded just like bowling but with office furniture. But for the most part as long as the unit isn't facing a major road/rail and the neighbors aren't the college-frat sort, they're usually not too noisy at all.
