A half American, half Parisian family of four move from one of the most cosmopolitan locales in the world to a city that is arguably even more so. As expensive as Paris is, London has a cost of living that is about twenty percent higher. But this glamorous family is not accustomed to dour living quarters. Their search for a proper flat for their two princesses takes them first to a maisonette, then to a traditional row house and, finally, to a Mews. Along the way, British charm chips away at the hold that Paris has over them.
