At the exit of the village towards Pointe Noire, after 3 turns take the first road on the right after the bus stop (direction chemin de Pointe Batterie), go down the road and after three turns you will see a sign DOMAINE DE LA POINTE BATTERIE on your left facing the mailboxes.
You will have to climb to the top of the Pointe Batterie and the villa is on the 1st staircase on your right.
