I think you're displaying a somewhat American-centric idea that other parts of the world are a step down. My God, if I was given the chance to move to Barcelona, I'd snatch it in a heartbeat.
You also might be surprised that Barcelona is actually pretty English speaking, at least as the ubiquitous second language, and it has become one of those international enclaves where people who work jobs remotely (especially in tech) set themselves up and live a pretty good life. The food is excellent and not too expensive, there's great entertainment, especially if you like dance, and it's a very livable city.
And when we're talking about an actor who has only appeared on Broadway three times in the past 20 years (and has split audiences over whether her voice is still pleasant to hear), this is a plum gig.
