House insurance

Experiences in house insurance would be most welcome.

We hope to "complete" this year! (originally January, then Febuary, then early May) and I am expecting, when the notaire comes out of hibernation that he will ask for evidence of a house insurance policy.

I have obtained one online quotation of under 100 euros, remainder exceed two hundred euros.

The house is in a small hamlet. It does not have a name or a number. The most definitive identification is its "parcelle number" in the cadastral entry. Is this likely to cause great problems, or as many SurviveFrance Network discussions testify depends on location, and which side of bed I get out of.
