Croatia. I'm biased because I'm an expat croat but it's actually a good option. It's central in Europe, you could replace Croatia with Slovenia if you wanted.

Croatia. I'm biased because I'm an expat croat but it's actually a good option. It's central in Europe, you could replace Croatia with Slovenia if you wanted. It's still relatively cheap compared to the rest of the EU. There's a budding IT field and if you stick to the major cities you'll even find a sub-culture of makers and hackers. There might be better options out there but I had to mention it since I'm from there.
