I have lived in Paris for almost twenty years and had visited Montmartre numerous times but I still learned a lot from Robert. I appreciated his endless knowledge, his passion for the neighbourhood and the artists who live(d) there, and his patience.  I especially liked his singing in front of the guinguette Lapin d'Argile.  I also appreciated that he was willing to do the tour for just two people, under the rain, mixing both perfect French and native English.  The only thing that I would recommend is that he refrains from making personal (and often unwanted) comments about people which can be off-putting (regarding people's weight, hair, age, names etc).   
I regretted was that I did not have enough cash on me to pay him an extra tip. He definitely deserved it.
