My friend and I (two mid-20s women) stayed for a week in mid-September on our first trip to Paris (and Europe!). We couldn't have picked a better AirBNB for us. It is in the perfect location to make major attractions walkable (Louvre ~10minutes, Notre Dame/Latin Quarter ~15 minutes, D'Orsay ~25 minutes) and close to the subway to be at the remainder tourist spots easy to get to. It is in a "hoppin" area with lots of bars and young people. We never felt unsafe and loved the lively ambiance. With the balcony door closed it wasn't too loud either.
The space itself was clean, efficient and decorated very cute. Anne Laure met us at the door to show us the space and was very gracious. She gave us a list of recommended restaurants, a map of how to get to the attractions, and a bottle of wine! The door locks can be a little tricky, but with practice you can get them.
Overall, I would recommend this AirBNB!
