>so I would like to hear what's necessary to charge something like 100-150 euro/hour -

Embedded, especially small footprint (32kb ram and that kind of thing) is an easy one.

Enterprise senior dev pays more than that as well if you are good. I ran gigs in Munchen for 150/hr and German friends of mine still do.

However 60k is that salary and is that gross or net? Think you are comparing apples and oranges; in the Netherlands, and Germany does not seem very different in that respect, if you get 60k salary, the company is actually paying more than 120k for you. So if you convert that to freelancing, you should be charging at least that 120k (which is less than 70/hr).
