Nope, truely peaceful and quiet with a bicycle trail/pathway trail straight into the bukit timah nature reserve. You want to know whether it is true or not, make a personal visit there but don't go to the showflat, drive deeper into the apartments (Chestnut apartments or something like that).
Deeper into the road and listen to all the traffic noise and what not - as that is even closer to expressway. Thereafter, walk out and walk further towards the expressway, go under the expressway then go right to real deep end, think it is linked to a "well known natural bicycle trail into the nature reserve" - Go explore
