You helped me a lot. It is really difficult to understand these issues from outside.
Thanks again...
Actually, i have many questions in my mind but will ask a final question only.
If I am offered this position, which housing option is better for me?
Live a flat like below in central Paris (close to OECD) or live in Paris suburbs?
A furnished flat or unfurnished one?

Also, I do not speak French well so I will need an English speaking real estate agency to rent a flat or house. Do you have any suggestions for me?
