What is the author's tone in Paris to the Moon by Adam Gopnik?

Enthusiasm and even joy permeate this book, in which Gopnik fulfills a lifelong dream to live in Paris. The eagerness with which he explores the city, its ambience, events, history, and contemporary issues, is infectious. Gopnik quickly confesses great love for the city, and then does everything possible to draw the reader into his embrace of Paris, to make the reader complicit in this love. He is not uncritical of Paris, however, nor is he reluctant to address what he perceives as its shortcomings. One recurring example of his displeasure is in the officious, inefficient nature of French bureaucracy, which he encounters frequently in dealings with government employees.
