Please bear in mind that you do not live in an isolated whole space. Instead, you live in a room which is part of the house with the host, her two sons and a dog (they are all adorable). Also, when you enter the gate of 18 Rue Cuvier, it is the green door on the wall at your left hand side (looking from outside it is dark and looks like a discarded space, but don’t hesitate, it is the right place). Don’t cross the yard. It is not the white building behind the yard although it looks more like an “appropriate” house.
