We had the pleasure of spending a very long and wonderful day in Paris with William in July 2013. It was easily the highlight of our trip to France. William was fantastic with our two teenagers and was able to easily switch from light conversation with them to fascinating discussions of French culture, politics and history. All of this while combing almost every part of Paris on foot, bike and tube: from the Champs-Elysees to Le Marais to Montmartre. Thanks to William we have a lifetime of wonderful memories from the City of Light. We would not hesitate to recommend him and to hopefully meet him again when we return.
