The being offered is a good one. Since the company is taking care of most of your major expenses, you'll hardly get to spend much. If you live a normal life, you may get to spend QR 5000 at the most on your expenses. This of course depends on your style of living. As for demanding a higher salary, it is all up to your negotiating skills. But I believe the company may not yield to your demand as the package itself is a pretty good one.
