As compared to Dubai, the cost of accomodation inside doha for a 2Bed room hall apartment is almost same i.e 7000-9000 per month as per location and condition. However if u r living outside Doha then u will get the same thing in little bit less price i.e 5000-7000

As far as transportaion is concerned it is less expensive then that of Dubai bc of fuel price and less places to go for outing.

Food is again same price as that of dubai but little bit costly in big restauratns and malls especially for asian foods

Altogether, u dont have to bother about the expenses as it is almost same as that of Dubai. However, u will require more time to adjust here bc of inferior infrastructure of the city as compared to Dubai
