Thanks to all, for your help so far.

As I said, after the initial three months, the company would not be helping towards the accomodation costs. So, basically, my wife and I would be spending just over half of our joint income (say 19,000 of 30,000aed) on rent. We would be able to pay for the entire year in advance, that would not be a problem.

That would leave us with about 11,000aed left over each month between us. By my calculations, that's about £1,500GBP, which would be a reasonable amount to play around with in London each month.

In your opinion, is this enough to enjoy a comfortable life (eating out two or three nights per week, a summer holiday, shopping etc), plus allow us to save a little too?
