Staying at Helene’s place is among the most authentic Parisian experience you can have. Hélène and her husband and very welcoming and helpful, and the location in the hearth is the 7th arrondissement is great. You sleep in a top floor « chambre de bonne » (service room) - previously used as an office - where you have a sink and toilet. The room is on a back courtyard and very quiet (even if next to the mechanical room of the elevator, which is not much used at night). The room is only accessible through a service stairs. The owners let you use their bathroom and kitchen, 3 floors lower, requiring you some exercice (no lift) and a brief outdoor transit. All this make the stay very original and did not bother me at all.
