As nolimitholdem said above, the EK accommodation department is run by people from the sub continent. 8 people living in a 1 room hovel is perfectly normal for them. Do not expect understanding or sympathy for any of your exorbitant concerns about your palatial accommodation, temporary or otherwise. It will be your first lesson on living in Dubai. You are actually much more privileged than 95% of the other people living there and the underprivileged will never understand what you are unhappy about. You will learn to make do and put up with crap in order to get what you came for. ie give and take.
Sooner or later (hopefully later) you may have achieved your goals and or just can't give anymore. So you leave.
It's your choice whether you get upset about things unexpected or others attitudes toward you. The more tolerant, and resilient you are to crap the longer and happier your time in the middle east will be.
If you spend your days reading your contract to ensure your company is not cheating you, overworking you, or infringing your seniority rites then the middle east is not the place for you. You will not last, and you'll find it impossible to enjoy what there is there.
If all you want is a reasonable lifestyle and a job where there are still opportunities for advancement then consider it.
