I'm currently giving serious considering to spending a couple of months living in Lille in northern France, mostly to try to improve my French. I'm planning to be there too long for just a hostel or hotels, so I'm after something more permanent. A flat/house share might be possible, but given the numbers of friends and family who've decided they'd quite like to come and visit, I might be better doing a short let on a flat.
I've had a look on Air BnB, and there are some suitable looking properties on offer there, so that's one option. However, I can't help but think that there will be more elsewhere, especially on French sites, if I only knew where to look! I might be wrong though, as I don't know much about French renting rules...
Beyond Air BnB, where should I be looking for a short (a few months) flat let in Lille? Any major websites to check? Any key phrases to google for? Any kind of special rental agency I should be trying to locate + speak to?
(Note that I'm not after "my friend Jim has a flat, speak to him", more like "almost everything like that in France ends up on website X" or "you need to find agencies that says they specialise in Y and work with them")
