Do you generally have to wait in long lines in Europe? I heard a few horror stories when I was in Spain this year.
I live in northern Spain and waiting times are not bad at all unless you have something really minor. For example I had to wait a couple of weeks to get some ecographies when they suspected I was developing kidney stones, and less than a week to get tested for celiac's, but I waited almost two months for the dermatologist, because my issue had no medical urgency whatsoever. That's how it works usually.
I'd say the Spanish health care system is top notch, although it varies somewhat by region.
