问题
I am French, and I am developing a rental vacancies website. I would like add microdata on the rental vacancy offers (house, villa, appartment...), but I don't know which itemtype to use. Offer, Product, or an other?
http://schema.org/Offer
http://schema.org/Product
Thanks for your help.

There are several relevant schemas that apply, and you will be best off using a combination of them to represent your Offers. The Offer should be your root element, because it represents something that ican be purchased for a price. The itemOffered property has the Product type, so it is the logical extension point for embedding product content. Think of the Offer as your sales pitch and the Product as what you are actually selling. There is a metadata schema for Residences which include information about the domain of your Products. You could combine this with the Product itemscope or nest it within the Product (possibly via the model property).
Metadata from the GoodRelations schema can be used to extend schema.org's limited Product vocabulary as well.
I also see an opportunity for leveraging the Review schema (for any reviews in the corresponding Product property), and potentially TouristAttraction, if the rental's proximity to tourist attraction is a selling point. I also noticed that there is a LodgingBusiness schema that inherits from Organization. This should be used to encapsulate content about your actual client (or whoever rents out the apartments/villas to renters).

Use the new version of schema.org (0.99) with the following properties for the http://schema.org/Offer:
- businessFunction; use http://purl.org/goodrelations/v1#LeaseOut as the value.
- eligibleDuration: The duration for which the given offer is valid.
- availabilityStarts: The beginning of the availability of the rental object.
- availabilityEnds: The end of the availability of the rental object
