actually all foreign domestic helpers are the same price HKD3320.00. Do not listen to the agency who tells you that you can pay less for an indonesian maid because it is against the law. Basically there is no difference, all depends on your luck.
Indo are stupid and really difficult to communicate, the said they understand cantonese, but i don't think so. And they do not speak good english, not easy to understand each other,
Filippino are smart and sometimes like to "play" tricks, but they are more clean and cooks better.
Good luck.
