The windows there were double glazed (good for heat and noise insulation), and I guess the walls were fairly thick as noise from neighbours was never a problem.
The only significant problem, and specific to that building, was the designers massively underspec-ed the cooling. So on summer days (29C -> ~44C) the air conditioning throughout the whole tower was completely useless. Sweltering hot. :(
I don't think it's purely a location-based thing. Not that long ago, Australia 108 became Melbourne's tallest building after surpassing the Eureka Tower in height. The residents there complained of walls that creak and crack like what you'd hear in a ship (which the 432 Park residents are also complaining about).
Somewhat related to that, when I was checking out apartments in the various CBD buildings, only the Eureka Tower ones seemed to have been built with any kind of quality or attention to detail.
Eg Surface finish of paint jobs was well done (even in non-obvious areas), gaps where surfaces join were consistent, and that kind of thing.
You could really tell it was done by people who gave a shit. Or at least, when looking at other places (Freshwater Place stands out), those ones were all clearly done by people who didn't. :/
So, the reports of problems due to potentially incorrect construction techniques in those buildings don't really surprise me.
In Australia, I used to have an apartment in Eureka Tower:
