The location can not be better if you are interested in staying in the 6th arrondissement. It’s perfect for a quick trip to Paris but I would not stay here if you plan to spend time in the apartment. The biggest issue for us was the cleanliness.
Also, as mentioned on Airbnb it is a studio so I would only recommend this for a couple or for 2 people who are comfortable with being in tight quarters.
Despite the location I would not stay here again.
