Italy, I have been there twice, I would go back on a moments notice. Italy has history, but it is also modern. It has a wonderful climate, warm, dry, with mountains in the north. It has food, glorious seasonal, local food. Wine, simple, unpretentious, drinkable. There are places I have been, and I would go back to any of them, there are places I have not been and can't wait to see.
Could I live there? For a few weeks or months, but I doubt that I could cope with the red tape on a long term basis.
