To reach Bourron Marlotte from INSEAD:

Turn right onto the main road (Boulevard de Constance) when leaving the campus.

At the roundabout with the obelisk, take the third road (D58, small road, towards Episy & Bourron-Marlotte), directly opposite from where you entered the roundabout.

Turn right after about 2km and continue straight ahead.

The road will take you to Marlotte, directly into the main street, rue Mürger, where the domain is located (at the very end on the left, next to the Pharmacy).
