Weixiu's apartment is within easy walking distance of many amazing sites in Paris (Notre Dame, Saint-Chapelle, the Louvre, the Pantheon and more), and has close access to public transportation (bus and Metro). There is a boulangerie around the corner, as well as many cafes. If you want to cook meals in, there are several markets and butcher shops within a couple of minutes walk.
Weixiu is a very gracious host, and we would stay at her apartment again. She was easy to communicate with, and quick to respond.
