I didnt spend so much time at Christophe's house, except sleeping, and we didnt have so much interaction. The house was very well located. The neighborhood was safe. Having the bath upstairs might not be very convenient as to avoid making them disturbed I wasn't willing to go upstairs much. They never made feel in that way though. I had no troubles at all, Christophe was so kind.
It's mentioned that they're smokers, but when you close your door, you dont feel it, and also re the restaurant kitchen door, yes it was noisy it was not as bad as I was expecting.

For short stays and limited interaction with the house and households definitely recommended.
