We stayed at the place for two weeks, with a baby. Eric helped us with the bad for the baby. The location is really good, and very close to the RER station, so getting there from the airport is very simple.
There is a small elevator that helped us with the stroller, its very small and can only fit a small stroller.
The apartment itself is as advertised, its a small place, with a small kitchen and a decent bed. Its fairly dark since its at the second floor. It wasn't easy to stay there with the baby but it wasn't so bad either. For a couple its a good place.
Only issue I think important to mention, there was severe smoking smell in the stairwell, and it got into the apartment too. Someone there is smoking a lot. Hopefully this will improve.
