Where to live in Dubai?

Moving to Dubai soon with my wife (early 20s) and newborn.

Looking for a 3BR in the city with a 300K AED budget. I want to be in the center of things but hate extreme noise and traffic. I love going on random drives and don’t want to be stuck in jams all day.

I work from home, i want to be next to cafes/gyms/shops/parks

Considering JBR, Downtown, and Business Bay—any better suggestions?

Can you also recommend me the best buildings in these areas?
