Hardly five minutes from the metro station (Line 8) on the outskirts of Paris (Maisons Alfort) close to the Bos de Vincennes (and the chateau). Near where the Marne joins the Seine so nice walks around the lock on the Marne and along the two rivers.
Nice little studio.
Supermarket and a couple of other shops nearby.
On the other side of the Marne and up the hill a bit is the main street of Charenton le Pont with brasseries, etc.
