I’ve lived in all four.
My father’s mother’s side is extremely old French. I grew up, with my brothers, when not traveling / living with parents [dad did a lot of travel due to his career] on our grandparents’ farm in the Picardy region of France. The farm has been in the family for many, many, many years [generations].
My mother’s cousin, well he (his brother & son too, and his father a savvy businessman), is a pilot with the British airways. He has houses in England, Barcelona (Spain) and Lagos (Portugal) & when working in these areas, I have oftentimes made use of his houses.
When I am not traveling for my own career, or like now visiting relatives in Canada for a family get together until 3/4ths into May, I happen to own a property [condo] with my partner/boyfriend in Florence that we got about 2 years ago.
So what exactly are you wanting to know?
I have travelled to so many places – first as a child with my parents, and then as an adult for my own career – that the “normal” concept of pro vs. con has sort of lost meaning. I am, after all, extremely adaptable. I am as comfortable in a tiny village as I am in a major city. So … what you find a con, might, for me, be hardly a problem.
As for the "ultimate" place I'd like to live would have to be somewhere remote, somewhere widely untouched by human expansion. I love cities; but ultimately, I am most comfortable in nature. So either my grandparent's farm or, as I have visited, the farm that my partner's parents own in their home country. Now that is fantastically remote, barely another house [or soul] for miles.
