Location can't be beat! Super walkable to everything on our list: Notre Dame, The Louvre, The Catacombs, The Tuileries. My husband and I fell in love with the old-world charm of this cozy flat in a historic building. Yangyang was super responsive to our messages and check-in/check-out was a breeze! The only thing we would change is the comfort of the bed (the mattress was a bit thin for us).
