This is my first experience on airbnb. So I was worried about many things. I didn't meet Her in person but Natalia was kind and accommodating and she gave me detailed directions. And cleaning lady was very kind and welcomed us.
First, location of the flat was perfect. The flat is 5 minutes from Terne metro, 10 minutes the arc.
We are three family including 4 and half year boy. If you don't have little child, time gets much shorter. It's very convenient location from the CDG airport and to the Eiffel , gare de l'est , nord and Lyon , Montmartre and even Disneyland. There is everyday Parisian market couple of meters from the flat. There are so many delicious fruit and food. Also have famous bakery "Paul" and many other bakeries, cafe and restaurants. And two supermarkets and one very big supermarket. I could save my budget and feel like real Parisian.
Second, the flat itself was great. It's newly renovated and well equipped. It was exactly same in the picture and very spacious and clean. There were everything that I needed. I felt like my home.
Third, the flat was safe. There are three locks - two kinds of code locks and one key. And it's on 4th floor. We felt safe during entire staying.

If you want to feel Parisian atmosphere and stay at convenient location, I recommend this flat.
