What to do around Paris for a week?

Hello everyone,

I will be traveling to Paris next month and the final destination is Amsterdam. I have already planned the Netherland part and want your help in France 🇫🇷.

It will be 6 days in France then heading to Amsterdam.

I think of spending four days in Paris staying in hotel or guest house. The other two days to visit villages/countryside and staying the overnight (Airbnb) as I love nature.

Is this plan good? Do you suggest any alternatives?

Do I need to rent a car for the two days outside Paris (convenient)?

What countryside/villages should I visit near to Paris?

Should I stay the whole night in Paris and visit countryside (round trip)?

Note the plan is flexible I can add one more day or take some off.

Please advise 🙏🏻
