The room is in a quieter area of Paris – we never had any trouble sleeping at night due to noise from the surrounding areas. It is on the eighth floor and has plenty of space. It is located at convenient proximity from a subway stop. There are some nice things in the neighborhood within walking distances: places where you can buy fresh fruit and vegetables, artisanal bakeries at very reasonable prices, a park, and (within the park) a market for old and/or used books.
One more thing about the apartment is that it contains a very respectable collection of French books, on a variety of interesting topics.
