I stayed in Nicolas' airbnb for 5 days. Check-in communication was perfect and I was able to get into the apartment without any issues. The location is very convenient for visiting most of the major sites in Paris, and the metro is just a block away. Montmartre is a 10-15 minute walk, while the Louvre is about a half hour walk. I didn't spend too much time in the apartment but it was very comfortable and clean. Would love to stay again the next time I'm in Paris.
