there’s a complete list of free listing sites for french gites over at the lay my hat forum here: http://www.laymyhat.com/forum/viewtopic.php?p=89766#89766

additionally, you can list your site for free on my directory here:

Just head over to HERE and register and add your property. Should be pretty straightforward (there are also Frequently Asked Questions pages to help) but any problems there’s a contact form there as well. Although the site is Dordogne based, visitors to our Lot-et-Garonne site will be sent to the same section, so it should work well for both departments.

please send me more info re how to join your site

thanks in advance
