Your type of apartment is a very luxurious one. Only people from high society can afford such things. Some may find 15,000QAR monthly reasonable and some may not. Different persons compensation varies from their job and the company they are working for. You may earn about 50-60 thousand QAR. And some may only have 5,000QAR a month and live in just a simple apartment (2 bedroom apartment , unfurnished, and have to cover bills and water payments) just not located in the Pearl. Quite practical but it leaves more savings for your family especially for future use.
Happiness doesnt come from expensive cars, clothes and apartments, Its the presence and completeness of the family that is important.
