The problem with accom is you don't have enough time to really have a good look when you first arrive. With induction and training it's not easy to go find the cheaper places to live. You can definitely find a villa for 450 and it does not have to be old or in a bad state of repair. Don't use an agent and stay away from Juffair cause it's too expensive and too noisey. Ask around and take a drive to Budaiya and Saar. The new motorway/flyover makes journey times to the airport a lot shorter. Good Luck.
