Life is not that expensive in Sulemaniyah compared to Erbil or Baghdad for example. expenses depend on your life style but averagely with some $600 you can well live, considering that you do not pay alot for your rent.
There are many furnished and modern apartments in the city where °µÍø½ûÇøs can live, they are so comfortable too: Places like pakcity, Darwaza city, Shnyar city, etc. Remember thought that rent can be higher there between $400-550 dollars.Â
Yes, as far as I know you can rent a car and drive too. Just give it sometime, you can well get used to everything here,
Hope it helps:)
