I think anyone who when young has moved to a foreign city, especially alone, would immediately recognize and appreciate the truths apparent in this film. Certainly everyone's experiences are different but some things, the initial disorientation, the difficulties and pleasure of adapting to a new and very different set of friends, the joys of eventual acceptance and adaption of a new routine; these are probably universal. This film depicts all of this very well.
The Spanish Apartment rings especially true for me. Almost ten years ago I moved from NYC to Antwerp for one year then on to Barcelona, where I am living still. I was a bit older than the film's characters (late 20 's) but my experience was eerily similar. I lived just blocks away from their apartment, in Raval, and recognized many of the streets and locales. Myself, a Slovak girl I was dating, three male apartment mates from Bolivia, France and Italy. I made tons of expat friends from all over Europe (many of whom departed long ago) and eventually Spanish friends as well.
I'm older now and settled down but watching this, I was overwhelmed with nostalgia and wished that I could travel back in time if only to relive one of those glorious weekends.
If you've never done anything like this watching The Spanish Apartment may be the next best thing.
The Barcelona tourist office should probably pay me for this.
