Have a look at Google Maps (although it's a bit ouf of date) it will give you an idea of the lay out of the town.
Where you want to live might depend on what you are planning on doing in your spare time - alot of the social activities are based around the Qurm, Medinat Qaboos area.
Qurm is quite a drive after a night shift (7am finish) when you are fighting the rush hour traffic to get home.
Areas where some of the controllers have/are living in are:
Al Hail, Al Azaiba, Al Ghubra and Bawshar.
It used to take me about 20 minutes from Al Ghubra on a good day and the worst day was 2 hours (after some rain).
