From The Movie Snob:

L’Auberge Espagnole. (B) Xavier is a French economics student who needs some direction. He signs up for the Erasmus exchange program and heads off to Barcelona for a year, leaving his girlfriend (Audrey Tautou of Amelie fame) behind in Paris. At first he stays in the apartment of a French couple he happens to meet at the airport, an arrogant neurologist and his gorgeous wallflower wife. Then he finds an apartment with five (eventually six) other young people, each from a different country, and the movie is largely about their multicultural friendships and romances. Except for the film’s troublingly casual treatment of an adulterous affair (what do “sophisticated” Europeans think about us poor Americans when they see a searing depiction like Unfaithful?), this is an enjoyable entertainment.
