I know Al Qusais. There is 3 or 4, 12-floor buildings there where cabin crew lives. It is not in the center. So you will have to use more metro/taxis to move around.
But the airport is not far from there.
THe nearest mall is the Deira City Center. 15dhs if you get a cab.
The nearest metro station I donn't remember exactly, can be wrong but I think as far as metro stations go, you have to walk a bit to get to them.
