Emmanuelle's place is exactly as it appears on the airbnb site, and all of the 5-star reviews were accurate. It was a great location for getting around since the Metro/RER station was right across the street. There are many great shops and restaurants in the area, too. If you want a break from the train, it is about a 30 minute walk to Notre Dame and the Seine, but the walk is nice and you can even pass through the Luxembourg gardens on your way.
The apartment was clean and comfortable, and Emmanuel and her husband (who live in the apartment right across the foyer on the first floor of the building) were very welcoming. It is a small place, but much nicer than the small hotel rooms one usually gets since it is two levels with the bed and bath at the bottom of the spiral staircase and a small kitchen/sitting area when you enter. I would highly recommend this place for anyone who wants to get around Paris and feel at home at the same time.
