There is no way of telling how much a room attendant gets in a five star hotel in Qatar because these hotels pay differently. Again, there isn't anything available on this as payment details are rarely made public.
The exchange rate is 1 USD to 3.64 QAR (Qatarian riyal) The closest i could find for your answer is a hotel waiter. The national average wage for them is 37.46 QAR per hour which would come out to around 10.00$ USD. That may or may not include tips since tipping is done differently outside the USA. okay. i found a reference for room attendant at a rate if 1500 QAR but it doesnt say if thats by hr day week or month. (412$USD)
