Find out hwere you will be working and then find a place near, or on the right side of Doha, traffic can be a nightmare. Rule of thumb all the western ex-pats tend to stay in the north and west. Judging by your name then likely you will fit in there.

The airport in in the south as is the power station.

Doctors are not a problem, there are local health clinics everywhere and then there is the HMC, the Hamad Medical Corporation. Conicidence?

Get in a compound if you can then you just yell at the manager to get this fixed, which you will need to do a lot....

Happy house hunting
