We stayed for 2 weeks at Jeannine's place, and it was a great experience. The place is exactly as described, spacious and cozy. It's on the ground floor with a small terrace, which is a plus for us since we have a 1,5yo girl that like to sit and play outside.
I was a bit worried for the temperature because i've experienced parisians hot summer, but apparently the place has a nice pleasant temperature. Since we stayed long, Jeannine offered one cleaning service, which is very nice :)
Jeannine was a truly super host, she is super nice and friendly. She asked regularly how we were doing, and managed to accomodate our special requests for baby equipments. We were so happy to stay there and surely will come back next time we are in Paris :)
We would highly recommend her place to stay in Paris.
