My two favourite things in Paris were:
1. The Coulée Verte/Promenade Plantée – an elevated walkway built on top of an old railway line that runs above the city from Bastille to the Bois de Vincennes. A garden in the sky, if you will.
2. Sparkling water fountains! Ice cold sparkling water! For free! Welcome to the future.
