Perfect, utterly perfect sidecar tour--and great staff!
I ordered a private sidecar tour as a surprise gift for my parents, who would only be in Paris for one day to celebrate their anniversary (!) When I called Left Bank Scooters, they told me that they were fully booked for Monday.
Here's the amazing part: at my request, they offered another group a discount to switch places with us! They were gracious, efficient, and accommodating throughout this whole ordeal, and basically worked a miracle to arrange a tour to my exact availabilities. Hats off to them.
As for the tour itself--you should read the other reviews. Thierry is a master who knows Paris like the back of his hand. According to my parents, he was a charming and knowledgeable guide, and greatly enriched their appreciation of Paris, in style.
This sidecar tour is a great, novel idea. Left Bank Scooters executes it to perfection. They are absolutely worth the price, and would be worth twice it. Highly recommended.
