I worked in the Paya Lebar area for a year (around Upper Paya Lebar Road) and it would NOT be my choice as a place to work in. (Working there kinda sucked too.) You might possibly be thinking of the Serangoon Gardens area which is quite near there. Serangoon Gardens is a nice area with lots of low-rise landed
property (houses), cafes and so on but not so great if you don't have a car.
I personally consider the East Coast to be one of the nicest areas for expat familes, with lots of outdoor amenities including parks and the East Coast beach.
The usual rule for choosing a home applies though: come here and stay in a
Serviced Apartment for a while and TAKE YOUR TIME about finding te right place to live. You will never get the true sense of a place or area by trawling around the internet forums. (Even one as well informed as this one!

)
