We stayed at Anne-Katerines house for 11 days (September 2013) and it was a great experience!
The house was just great - looks even better then in the photos: spacious, very neatly designed, very quiet (an inner house) but central so we really felt parisian for these days - EVERYTHING within 1-3 minutes walk: metro, boulangerie, supermarket and all the rest of the small shops so common in Paris.
We were a couple with 4 kids and they felt so at home it was hard to make them leave the house and stroll the city.
The most important is that we were welcomed very heartly and warmly - even before arrival we were told "my home is now your home" and the reality was exactly like this (including small details such as asking us if we need anything special as food etc. for the first day).

We really cherish the time at this house - great experience and great host !
