If you have any doubts, leave them and book this experience! Having done both the river cruise with 200 people and a private boat cruise, the experiences were not even comparable. I could not say enough good things about Axel and this experience. I let Axel know I was planning to propose to my girlfriend during the experience and he was so incredibly helpful with the entire process and went above and beyond to make sure that the proposal went smoothly. Axel is incredibly friendly, knowledgeable and fun guy to chat with. There was never a moment of feeling uncomfortable. He also made sure that we got a prime view for the Eiffel Tower evening lights and provided some refreshments as well. 100% would recommend.
