It's a nearly suburban station, Javel, not the most glamorous of places. You can see the towers of Grenelle behind the train which are generally thought to be a disaster but some of them aren't too bad.
It takes its name, I believe, from a local manufacturing plant which produced the famous eau de javel, otherwise known as bleach for keeping your floors and toilets clean, and your clothes bleached too I presume.
It's also one of the best stops for hitting the Parc André Citroën which is well worth the detour.
And why not...
