Heading towards Rue Des Pres trading estate from town, turn left directly after Longueville Manor into La Rue St Thomas
Stay on that road for 500m until you see the old L’emeraude Hotel on the left hand side 
There is a left turning called ‘Route Des Champs’. 50m after that there is the hotel and on the wall are some signs for businesses, SAS is the silver one at the bottom
Turn where you see the signs and drive between the buildings
You can only go left, then right, and drive directly ahead of you up to the units, my sign is forward facing and lit
