Villa for 10-12 people in Provance

Just rented one for 8 people in St. Jeanet for mid-July through Homeaway.com. They have a ton in all price ranges. In our case, we are dealing directly with the owner and it's been smooth and easy, so far.

I can recommend Mas L'Authentique for your group. It is within a short hike of Eygalieres which has 2 bakeries and several bars and restaurants. Its also only about 6 km from St Remy so location is ideal. We dealt directly with the owners a few years back and have no experience with the current management.
We managed to squeeze in 12 adults but it is a rustic place with no two bedrooms the same and best suited for 10. I can't endorse the location highly enough--you will love Eygalieres. The pool is delightful and has a fabulous view of the Alpilles and ruins of Eygalieres.
Good luck.

Stayed here in 2006 with 11 people, will sleep up to 14. Still one of my all-time favorite rentals. Near Ménerbes in the Luberon. Website in French only. Owners are Swiss. Let me know if you want a translation or more info.

I just googled "provence villa rentals" and came up with this:

There were several other results but I think you get the idea. You also look on the gites-de-france website or abritel.fr or homelidays.com or any other number of websites that do self-catering accommodation.

What is the configuraiton of your group?

Many of the villas assume that there will be several kids and provide 1 or 2 bedrooms with bunk beds or twin beds. Fine for smaller kids - not if the group is all adults.
