Our family (2 Boys, 8/11 yrs) had a perfect week in this place. The location is totally quiet, deep in the forest. The house is fully equipped - not luxourious, but very charming. If it would have been summertime, we could have made more use of the garden.
As we aimed at visiting Paris (appr. 1 hour with public transport from Persan), this location prooved to be great for us: one day in the busy city, another in the quiet forest, and again...
We can fully recommend this location, but please consider: you should have a car / no WLAN or else / urban boys might fear the forest by night.... ;)
