My uncle moved from Germany to Portugal for the same reason. He loves it and the main pain point is healthcare - low-cost, but in his 70s he travels back to Germany for health issues due to quality. It's unpopular opinion in Portugal and everyone will tell you how nice the hospitals are, zero wait times and no hidden expenses. May be my uncle was unlucky, but minor heart issue wasn't properly diagnosed for about a year there, and required a single visit in Germany to get it under control.
