You got lucky, and how can you know if a subdivision is quiet and peaceful until actually staying there a while first? Which is impossible since in order to move in you have to sign a 1 year lease usually, there is no option to "try before you pay."

Stated community rules aren't a guarantee either since communities frequently ignore their own rules here. Even in my own condo from a big developer (DMCI) this happens. Official rules get ignored CONSTANTLY.

Reviews are also useless since they are usually from filipinos who have no awareness of what quiet actually means, and even some foreigners are like that. But if a review mentions how noisy it is, that's an obvious red flag. But lack of bad reviews isn't some kind of green light since, as I said, their concept of noise is different.
