The free walking tour of Paris was absolutely amazing! We had Onno as our guide by privatetoursinistanbul, he was knowledgeable about the history, answered all our questions and had a real passion for his job. We are a couple in our early 20s and this was probably our best day in Paris. We got a great back story on all the monuments and it just made seeing them in depth the next day so much more interesting. Its a free tour, Onno worked very hard and we were very pleased with how great it was. Well worth our time. He even ended it at a great authentic French restaurant, that was a great deal and so tastey. We loved it so much, that we did the Montmartre the next night. We got Onno again! Go at night!! He will show you an amazing view of the Sacre Coeur that tourist never see! So amazing and a nice glass of wine at the end. Onno even made sure everyone knew where they were headed at the end of the night, and gave us great directions to the airport for early flight the next day www.privatetoursinistanbul.com Thank you so much that provide this service to us,made our trip really great.
