Emmanuel's flat is located in a great location. It's close to a busy street, but I was pleasantly surprised that you don't hear the noise once you reach the flat. There's a few cute coffee and tea shops in the small streets around the flat--be sure to check those out. My husband and I walked to all the main sights in Paris, and it was good that the flat was in a central location. It's also quite easy to get to the flat via metro from Charles de Gaulle airport.
The place was clean, and Emmanuel responded to my questions promptly. Would recommend staying here!
