The house is like we see in the pictures and the location is the best thing of this house.
My recomendation is before do the reservation, confirm the hours for check in and check out, or else, you can spend a few hours walking around Paris with your bags...
I rent the house for 3 days, for 3 persons, with an extra bed, and when i went into the bathroom i just saw 1(!!!) toilette paper for all of us.
In terms of the cleanliness, it was possible to see some traces of use from the previous guests, in the room and in the bathroom.
