Antoinette is a very lovely person. I stayed at her place with my boyfriend for 4 nights and we really enjoyed our stay. We were warmly welcomed, given advice for our Paris expeditions and were encouraged to speak French - as she doesn't speak English (yet :)).
Her apartment is comfortable and clean - I only stole one star in the rating of the cleanliness of the bathroom because after all it is a shared living space, not a hotel, so minor stains are unavoidable. It is located in the heart of Sacre Coeur - very convenient for exploring the city on foot.
We had a great experience staying at Toinette's place and would totally come back any time. Definitely recommended.
