Many retirement destinations are promoted on the basis that they're 'just like the United States'... touted for the fact that living there you'd be in familiar surroundings. That's not the case with Cuenca, Ecuador. Walking these cobblestoned streets past the historic Spanish architecture and the old colonial churches, you know that you're not in Kansas anymore.
One thing to remember about Ecuador is that this country uses the U.S. dollar. For an American retiree, this means it's easier to understand what things really cost; it's easier to keep track of what you're really spending, month to month; and, very important, you don't have any currency-exchange risk.
