This was my first time using air bnb and I'm glad that I stayed in Natacha's home.
Natacha & Thiery are very nice and they would ensure that you got everything you need.
The room is just like what you see on the photos posted, so nothing are being over promised.
The house had the warm feeling that you would feel relax and not reluctant.
The location is great, you get access to 2 train stations (Gare de Lyon & Paris Austerlitz - though the last one is quite distant), 2 Metro station, and bus stops within short walk distance.
And the neighborhood is also nice, that you will feel safe to walk home during night time (my experience was until 21.00pm).
