Great place overall and suitable for 3 people.
The apartment is spacious and very clean. The beds are comfortable.
There are all the cooking utensils available if you want to cook at home.
Our check-in was pontual, and although Charlotte and Mathieu couldn't receive us, they send their friend to meet us and to explain everything (they even send us some croissants and a baguette).
The area is nice and calm with many restaurants and a few supermarkets nearby.
A bus to the city center (Notre Dame, Louvre, etc) stops just a few meters from the house. There are two subway stops around 10 minutes away and also a RER stop, that leads you directly to all the main attractions (Tour Eiffel, Musee d'Orsay, Louvre, Notre Dame, etc). You can also use the RER train to go directly to Versailles (around 7,5€ round-trip) or Orly Airport (6,35€).
