We had a wonderful time staying in Frederique's place. It's location is superb as we could walk to the Louvre in about 20-25min, walk to the Eiffel Tower in about 25 min, and were about 2 minutes from the bottom of the Champs-Elysees.
We were six people (including two children) so we had to sleep two people in the living room. Both sofabeds were very comfortable and easy to open and close. The kitchen was well-equipped and allowed us to cook breakfast and a couple dinners when we were too tired. There's a Carrefour City market nearby but also google Marks & Spencer food as it's slightly closer and more prepared food - the Carrefour though has beer and wine while Marks just has wine. What was the nicest was being able to all sit in the living room comfortably after a long day walking around!
We would stay there again!
