After having lived in Jumairah for 3 years I know Dubai Life is expensive but quality which is worth the money...Amazing is the word.
Dubai infrastructure is one of the best in the world and life is Dubai personally was better than doha...

In Doha land prices and rentals are spiralling fast out of control and Im sorry to say for the money (3500 QR) that you mentioned you might not get a decent studio apartment.

If Doha doesnt do enuf to control its spiralling prices Im sure the bubble will burst soon and end up becoming counter productive for Dohas future.
