Welcome recommendations of these for Paris, Fall.
Last time, I took one with Paris-Walks (Montmartre) I quite enjoyed--no reservations, just meet up and pay about 12 Euros. I am planning to take more. Any you particularly enjoyed?
I just read of City Free--these I think you take for free and tip. Can anyone tell me what you tipped? Shall I assume 10-12 Euros? Any you recommend?
Others? Thank you.
