I stayed in this apartment for seven days. I come to Paris every year and have stayed in hundreds of Airbnbs.
First, the good. This is a great location within a block of the Metro, near lots of cafes, grocery stores, and shops in the 6th and about a 10 minute walk from Luxembourg Gardens. The bad: the apartment is dark, dank, has an odor, and is unusually small, even for a studio in Paris. I asked the host about the odor and asked him to do something about it, he did nothing. The shower is very good, but the bathroom is tiny, the sink is hard to use because the mirror comes out too far from the wall. The toilet makes flushing noises all day as the basin has to refill due to a leak.
The apartment does have a good washer and dryer.
This is a first floor unit whose window looks out onto the street, so there is no privacy if you want to have the window open - there is also no working AC in the apartment, so it gets very hot in the Summer.
If you are a couple, this place will absolutely be too small for you. Even if you are traveling alone, it will feel small and uncomfortable. The closet work from front to back and not side to side, so it is quite impractical to hang clothes. The bed is comfortable.
The host leaves no paper towels, no extra trash bags, only one roll of toilet paper. There are plenty of towels.
For the price, you can find much better in Paris, even in the 6th.
