Pros:
1. Great location near several metro stations and many shops and restaurants. This isn't a touristy area, so the prices in cafes and shops are reasonable, and the service is friendly.
2. Eiffel Tower view from the bedroom and kitchen!
3. Super-responsive host, great arrival and departure instructions and tips for the neighborhood.
4. A 20-25 minute walk from the Eiffel Tower, five minutes from Starbucks, and 10-15 minutes from at least three metro stations. 15 minutes walk from a RER station that will take you directly to Versailles. We walked from the apartment to the Musee d'Orsay, it took about 45 minutes. Lots of shared bikes and scooters available nearby.
5. Very quiet, with little to no street noise or from the neighbors.
Cons:
1. The apartment is in a residential area, not a touristy area. We loved this, but some may want a more toursity/commercial area.
