My stay at Pierre-Olivier's apartment in the heart of Saint-Germain des Pres was perfect. Located diagonally across from Les Deux Magots, it's location is ideal for walking anywhere, or using the Metro or bus system. Monoprix market is right around the corner as well as a magnitude of boutique shopping in this popular arrondissement.
Be aware there is no lift, but the stairs were part of the charm of this authentic location. The apartment is clean and fully equipped with anything you might need. The bed is comfortable and there is plenty of room for two people to live nicely for a short or longer stay. Communication with them is instant and very efficient.
I will definitely stay here or in one of Pierre-Olivier's other apartments when I return to Paris.
