Most apartments in Doha are fully furnished. Villas can be un-furnished, semi-furnished (includes A/Cs and kitchen appliances) or fully F. Good availability for apartments. Prices depend on area, quality of finishings and any extras (pool, parking, gym ...)
The 'little Venice' part of the Pearl is coming on the market next month - a mix of flats and town houses - huge. Not sure if it's all being released at once though. Bit of a trek from the Pearl to the airport but still manageable except at rush hours.
Consider if you really need a villa - the costs of electricity, water and cooling can be high. There are several good estate agents in town who will help you find a suitable place for a fee of usually 1/2 month's rent.
Serviced apartments are also available if you over-run the hotel allowance period and still haven't found a pad.
Fully furnished apartments include Bilal Towers & Bilal Studios which are only about 10 mins drive from the airport at most times of day. They will consider month-by-month but long term will of course be cheaper.
