It was very nice and cozy flat. And very safe, awesome neighborhood. And the location is also good. Near the pantheon, sorbonne, saint michel etc. I can find many hip reataurant, bar, cafe around there. You can stay as real parisian.
Most of all, the host Juliette is really kind and helpful. She replyed about my messages so quickly. And she lives in the same building so if you need her help she will come easy.
