NO,the offer is way tooooooo low. Your basic should be in the QAR 25,000 - 30,000. Check what accomodation you will get if not you will end up in a shithole in dusty area without any parking. Quality of housing is poor. Contact a western recruitment agency to confirm. Remember Qatar is not a developed country so you need extra compensation for that. Do not worry about the alcohol, join the locals as they know exactly where to go for the drinks.
