We stayed at Cecile's lovely house for a week in July with 2 kids under 5. Great Parisian house, well kept and a very central location- the train station was a few meters away, and a supermarket literally over the road. Apartment is 3 floors up and has a lift. Good kitchen. Big double glazed windows, which we could open right onto the street (which was a bit loud- but we had an unseasonably hot week so you wouldn't usually have them all open like we did).
Cecile was flexible, responsive and very welcoming into her home. She made us feel very welcome.
Toys, games and generally kiddy-proof so you can relax.
A wonderful stay.
