A real average Paris one-bedroom apartment like your acquaintance would let you stay while absent. Good sized bedroom and living room with kitchen area. All furniture and amenities for normal living, including a washing machine, used but in a good order. Quiet but bright with windows looking at the inside yard. There was a faint smell of tobacco in the apartment, but airing for five minutes with opened windows get rid of it. Apartment was very warm even if outside is almost freezing. There is no lift in the apartment so you need to take stairs to the third floor. The house is next door to Busenval metro station, 3 minutes to another metro line, and eight minutes to Nation metro with several lines, so getting around Paris was easy. The area felt safe even very late at night. There are several big and small grocery stores and small cafe next to the house, some of them are working after midnight.
Elodie was very welcoming and helpful. I enjoyed staying there and felt like home.
