You sound so Frenchy dude, I bet you're....Western community area ........ If you thinking like that then you better stay where you are ... It's Doha dude, You have to say bye to isolation and ******, open your heart to the Arabs man
You can find everyone everywhere, 20 years in the region, never heard such a thing .....
Try westbay if you can afford it or Compounds in Al-Waad, Plenty of Foreigners like you sir...
You can rent (long term) a small budget car from 1600/Month such as Nissan sunny or Kia picanto... Find them behind the baby shop near Mannai Roundabout...
Good luck !
