Thank you for your review. We are really happy that you enjoyed your tour, but disappointed that you left us a poor review due to extra money that Viator has charged you, which is completely out of our control. We are the local operator in Paris, Memories France, who organised and ran the tour for you, and we are very glad that you say we deserved a better rating for our tour! Viator are a marketplace that sells tours run by many different operators. They are the ones who take your payment and deal with all the charges you incur, we are paid simply the fee for the tour around a month after it takes place. We hope that any future guests reading this review will see that you really liked the tour, we and our amazing guides work very hard to ensure all our tours are 5* quality!
We are sorry to read that Viator have charged you extra and would like to confirm that we would not do that, there are never any extra charges during or after our tours, everything is always included. I'm sure you can check with them as to why this happened, their customer service is generally very responsive.
We hope you had a wonderful time here in our beautiful city and that we may see you again!
