I lived in the Czech Republic. It was hard going, but mostly because I was on my own. At the time, cost of living was very low, and it's a beautiful country.
I also lived in Bolivia. Loved it, but probably not what you're looking for.
I've always thought I'd love to live in Germany. The people are great, the health system is great, the supermarkets are great, the trains are beyond great.

I know a few people who worked UAE. None lasted longer than three years, but all loved the money.
