I'm a 25 yo French IT Consultant and I rent my apartment when I am away.
Price (very cheap for the location)
Location (quick walk to metro and Moulin Rouge)
Host (Vivien was very accommodating and prompt in responding to my inquiries)
Apartment was damp and smelled of mildew
Vivien is nice and the place is probably the cheapest in Paris. Easy to get around by tram with plenty of shops around the area. Be mindful that it is in the Red Light District of Paris so it can be seedy at night. Also there were no clean linens and towels so be sure to bring your own.
I enjoyed hosting him.
