Berlin, definitely. It is the best mix of everything you need.

Except sun light in the winter...

And you're saying that about Berlin? Try Finland, then :)

Yes, winters are an issue for much of Europe and especially for the northern part where much of software industry resides.

If that is important for you, then try the cheaper parts near Mediterranean - say, Slovenia is quite nice.

That really depends on the winter, but most have two or three sunny days, at least…

I've been told for the past three years that this is an unusually cold winter :-/.

Ok, mountains are not a "need", but Berlin is way too flat for me.
