My one and only time I've done a house-swap and it worked out perfectly. I traded my downtown Brooklyn for her artsy Pigalle and had a most rewarding introduction into Paris. For 10 days, I lived at the foot of Montmartre, my new favorite slice of French life-- filled with bohemian love, language and music. Of course, I saw the rest of the city, too, but somehow, the hills leading up to the Sacre de Cour beckoned me throughout my stay. Magnifique!
