Hello from the desert...
We moved over in February and so far it's been a good move for us (two young kids).
I'm about to fly home for the summer - it's really too hot to be outdoors between June - September, so that's worth bearing in mind.
It has plus points, and negatives too:
Pro's:
Good quality of life
Affordable home help and childcare
Sunshine! Pool time after school/work
Hugely accessible from the UK and a great place to travel from. The airport is excellent and plenty of fab places are a short flight away!
Nice expat community. Small town feel.
Tax free expat salaries, ultimately it's why most people are here, to save!
Relatively liberal compared to some Gulf states
Excellent place for young families. Lovely parks and playgrounds. Very very safe.
Huge villas/apartments. Lots of space.
Cons:
Too hot in the summer months, makes for long afternoons if you have kids and school finishes at 1pm
Driving - it's not as bad as you'll be told by many, but you need your wits about you. The air pollution is s bigger issue for me.
There is obviously a divide between Qatari's, Expats in skilled jobs, and labourers (many Indian/Philippino for example). How would you feel about that? There's no apparent poverty here, and new laws mean that everyone should be paid properly now (rather than not paid at all), but there is a hierarchy so to speak. That said, it's very multicultural and an aspirational place.
Shopping is pretty dire unless you're in the market for designer labels or run of the mill high street stuff. You can certainly get almost everything you need here, but food is quite expensive. The upshot of this is that I save more! And I look forward to stocking up on visits home.
Accommodation is very expensive. Standards are not brilliant (dated kitchens etc) and most compounds are pretty uninspiring compared to the likes of Dubai.
There's so much more I could tell you.... Anything specific you want to know??
