We stayed at Aline's place for 2 nights and it was a very good experience. Apartment is very convenient located, very close to several metro station and walking distance to Gare du Lyon. Easy to get from CDG airport. Supermarket Carrefour is in 3 minutes walking, a lot of options to eat right nearby. The apartment is on the 1st floor, so no problem to walk up, everything was very clean by our arrival. There are 2 rooms, both with sleeping places, so it can easily fit 4 people. Aline has all the necessary things in the kitchen, so it is possible to make food there. I would come back to her place for sure.
