Deciding what area to rent

Hello,

I will be starting a job soon at RCSI Bahrain and I will be flying to Bahrain end of the month. I am unsure what area to rent. Busaiteen seems cheaper in rentals price than say Amwaj or Marassi Shores. Another plus point is that it would be close to my workplace and I am dreading driving. However, there seems more facilities in Amwaj. Also does anyone know what a commute time I would need to factor in from Amwaj to RCSI Bahrain? I have looked on Google maps but I never feel the really factor in traffic conditions.

Any advice would be warmly appreciated
