The place is really well located! Walking distance from Saint Chapel Louvre and Notre Dame. And within just 2-3 minutes walking you can get the metro/rail station.
Francois was easy to communicate and also gave a lot of advices/information for our stay in Paris!
Just be aware that the sound insulation in the apartment is not very good, and since it's a shared apartment, it can be loud if people arrive late in the night.
Overall it was a very pleasant stay!
