I’d move to the French Alps, Annecy
Annecy, the old town at any rate is utterly lovely, and location wise it's fantastic too. Yup, that would do me very nicely indeed
To widen it a bit, I think half way down France in any one of the historic medium sized towns would be my ideal location. I am a bit of a Francophile, have basic schoolboy French, which I could work on if I lived there, and outside Paris at any rate, the French seem to have a great lifestyle and I've always found them delightful.
One of my abiding pleasures was going on caving or walking holidays in France. I'd tend to catch the midnight ferry or chunnel on the Friday after work, and drive as far as I could in the early hours till I was south of Paris, then stealth camp in a lay-by. The real holiday started at the next village and I had my first coffee and croissant.
