I have found for a single man in Doha that a serviced apartment is better. New towels and sheets 3-7 times a week. Throughly cleaned and presentable when the family arrive. You will be working long hours and maybe 6 days a week, the last thing you will want to do is washing, ironing and cleaning on a Friday (drinking at the rugby club day)
2 bed serviced apartment in 4 star facility with pool, gym etc etc is around 11,000-15,000 QRial per month
