Stephane's place was perfect for my boyfriend and I's four night stay in Paris. The place was right across the street from the metro, which was especially great for coming home late at a night and made it easy to get to anywhere in Paris. It was an easy 10 minute walk to the Eiffel Tower and you pass a street filled with shops and restaurants.
The place was really clean and the perfect size for the two of us. There was no air conditioning so it did get really hot (there is a fan though). Also, we could not figure out how to work the stove and when we contacted the BnBSitter about it she asked us to send her pictures of the stove and we did but then she never responded. Luckily a friend told us we needed to use a particular pan as it's an induction stove.
Overall the place was fantastic and I would definitely recommend it for your stay in Paris!
