To my taste:
Men: Italy. Yes, it’s a cliche but they are soooo handsome. Not sure I’d go out with them though.
Honourable mention: Irish lads can be real charmers, so that even when they aren’t that goodlooking, they seem to be. And I love that dark her with pale complexion and blue eyes thing that you seem to get here more than elsewhere.
Women: Spain. It helps that they seem to get really cool clothes out there, particularly shoes. Maybe that’s just me, but it seems that way. I’m female and straight, but I once worked with this Spanish girl who was so beautiful I just kept staring at her and would regularly lose my train of thought when speaking to her.
Honourable mention: Agreeing with everyone who said Finland. I haven’t been there, but my good Finnish friend is an utter stunner.
