We did this tour on 31/12/2016 and even in the freezing cold, the tour was excellent.
Our guide, Tom, was extremely knowledgeable and showed us around every place that you could think of and more. He knew all the spots to go to where you could get the best photos and was happy to take us wherever we wanted to go in Paris. The Vespa's were excellent to travel all over Paris on and we couldnt have asked for more from Tom and the tour.
I would highly recommend this tour as it was the best part of our visit to Paris and well worth the cost!!
