Thank you Laura for your comment, and to answer your strange problems: the location: you chose to come to us, so you know we're not at the foot of the Eiffel Tower ... :)
If you choose a location, you can not blame (or you). Or why not blame a sky for being blue or a tree for being green;). This is obvious. So it's a rating system for the location that I really do not find fair from Airbnb.
About the toilet, and the rest of the apartment, I really do not understand. Here too you have chosen a private room in an apartment. You rent a private room. If you want to have a whole apartment, then a simple way: I propose to rent an entire apartment, but be careful, it will not be the same price, especially in Paris.
We strive to respond as quickly as possible to people and always offer a place as pleasant as possible and that perfectly meets the expectations of travelers which is 99% the case.
Sorry if you made a mistake by renting a room and not an apartment. Good following you and we welcome you obviously with pleasure next time.
