Nicolas is a nice and very helpful host. He would always respond to my questions about my reservation. He even let me borrowed 2 usb adapter so we can charge our phones while in Paris. The location is excellent. There are so many restaurants, cafes and markets. I recommend eating at Les Saisons. It is walking distance to Montmartre. We felt safe walking in the neighborhood at night. The flat looks like the pictures posted and description. We were able to use all 3 metro stations near the flat and they are just 6-12 mins walking distance. We were happy that we stayed at Nicolas's flat and not a local hotel.
