Is the address of the house well listed on the GPS?
Yes quite.
For those who do not have a GPS, if you arrive from St Denis after crossing the bridge over the Saint Etienne river (or if you arrive from Saint Pierre by the 4 lanes), in both cases you will take the direction of the 'Between (RD 26). Arriving in the village, take the direction of Ravine des Citrons and you will be directly in rue Jean Lauret, until you find number 422 on your right.
