I'm considering an offer by a German company to move from Canada to Berlin.

What's the cost of living in Berlin for 2 people in their 30's ?
How much should I ask for (Gross & Monthly) ?
What are some of the pitfalls I should look out for ?

A few facts: There is a possibility that my girlfriend won't be working.
I will need to enter into the German tax system. We will need a car. I'm Canadian, she's German. Any advice would be greatly appreciated.

 

I appreciate the link. I'd already tried it out yesterday infact. But, since the tax rate between Canada and Germany is 20% different and it doesn't take this into account, I'm afraid it's not very useful.

In my own research I've seen that goods are numerically equivalent between the countries. That is, a $2 box of stuff will cost 2euro for the same stuff. Some quantities & quality varying of course. But apartments are 2500euro for a 2 room !! Wow! For $2500 I can get an entire house in Toronto. Maybe I have all I need, but more advice the better is my thinking.
