What sort of salary expectation should I have in Dubai?

I am looking to accept a job offer to work in Dubai in a couple of months. They have offered me a package around 23k AED, annual 2 ways ticket flight home for me and the family, 25 days holiday, school fee's, full medical insurance for the whole family, fuel allowance, relocation allowance and was wondering how do this sound? I have no kids so won’t need the school fee's. The office is based in jabal Ali so where would be a good place to stay? How much AED per month for a decent apartment are we talking? Accommodation worries me as ive heard you pay all rent for the year up front etc and i wouldnt have that kind of money. I plan to buy a car on a rental basis also. Thanks in advance!
