The best residential area for quality of life is West Bay Lagoon. You will need an accomodation allowance of QR20,000 and above to pay for a villa there. Choose from beach side villas with gardens and pools, park view villas which lead down to the beach, and mostly small compounds. The parks are numerous and well maintained and have flood lit tennis courts. The lagoon is great for running, dog walking, fishing, beach life, water sports, boating (and golf just outside) and generally good quality of life. Relatively dust-free though not sand-free!
You can commute to all areas of Doha - schools, offices, shopping areas, easily from the Lagoon.
