We stayed at Karin's flat from Apr 29th to May 3rd and it was our first experience with airbnb.
During the booking period Karin answered all our questions very promptly. We met her at the flat so she could give us the keys and she was very nice, she even bought us a baguette which was very thoughtful of her since we hadn't eaten for some hours.
The flat is exactly as in the pictures, it's clean and cozy and has everything you will need for a short stay. It is very well located, just a few minutes walk to the metro and you can easily get to the main attractions in Paris. It was also very easy to get there for CDG airport.
Karin is a wonderful host and if you are considering bokking her flat go ahead cause you will not regret.
