Everything was fabulous. Olivia is a great host. The apartment is great, exactly as described and it has a great location. We were 5 (2 adults and 3 children) and we loved the neighborhood, which is very calm and you can find everything you need in a walking distance.
To reach the nearest RER Station you can take a pleasant 5 minute walk through the Montsouris park, located in front of the apartment.
I definitely recommend this apartment and would definitely stay again.
