This is a perfect example of why you have to check the reviews before making a reservation. I didn’t do it and I regret it. The room is not clean: the floor is sticky, it doesn’t smell good, there is black mold in the walls, the bed sheets weren’t clean… The bathroom was also pretty dirty, with dog pee on the floor and dirt in general. Dust were not only in the shelves but everywhere, it is NOT a pollution issue, I live in a polluted city. It’s a no-cleaning issue, I refuse to believe that the owner ever clean, and if he really does, he doesn’t know how to.
The advert says that you have a lock in your room and it’s not true. It can be opened from the outside. Also, to enter the room you have to go through the bathroom, so if someone is using it you cannot get in or out… (that doesn’t happen to me anyway, but is important to know).
Now that I read the reviews: “this is Paris” is not an excuse not to clean and to lie in the advert and in the answers of the reviews.
