If you're looking for a truly unique and personal Seine River cruise, book with Axel. My friend and I were fortunate enough to have the boat to ourselves on a sunset trip and it was one of the highlights of our stay in Paris. Our co-captains made sure that we saw all the important sites and took pictures for us. The departure point for the cruise is a little out of the way, due to rules on the river, but completely worth the trip. I've already recommended the trip to other travelers, and would book this again if I am back in Paris.
