22K is good, housing is expensive, cost is 6 to 10K/month for anything worth living in. QF is a good place to work but job security is shaky without a good long term contract. They do tend to replace Expats with Nationals on a frequent basis. You train the local, they let you go and replace you with a Qatari.

If you have to pay all your living expenses from the 22k, not so good.
