Karen, Xavier (and the super-cute Theo!) were fantastic hosts. They were on hand to answer any of our questions, and were full of great tips from farmers' markets to a recommended route for a shakeout run pre-marathon.
The apartment itself was beautiful, and filled with light. It's located across the street from the metro, and the Rue de la Pompe was packed with shops and cafes. We also did a lot of cooking in the kitchen, which was better stocked than our own :)
It was an absolute pleasure to stay here, and we'd highly recommend it!
