It was a good walk from Paris Gare de Lyon, but easy to find.
The instruction to enter the building was not clear. As I kept receiving SMS from Al (presumed co-host) telling me to click on [xxx] on the screen, I asked him how to enter the building. Then, he said "You're a wrong person. I don't know you." I could finally talked to the host's portable to get the code for entering the building. It's not easy to find her apartment even after entering the building.
The room and bathroom were spotless clean.
The room only has a bed and clothe hanger. No desk, no chair.
The hosts were courteous.
