Nicolas was not quick to respond, I had to cancel my trip due to a storm and he did not respond until the next day in the afternoon, the only person to respond was a student he had hired to give us access to the apartment. After I canceled my visit to Lyon he continued to send me messages stating that he hoped i had a nice first day there, I asked him about these and he eventually responded that those where automatic messages. So the best communications that you get from him are automated programmed messages, but not a real person to respond to your concerns. What bothered me the most is that Nicolas wrote a review of my stay (I haven't been able to read it yet), even though I never stayed there. I wonder if his reviews are also automatic pre-programmed messages. It's too bad because the place looks great.
