What should I ask my prospective landlord?

After a week of tearing my hair out trying to find affordable lodging in Paris, I think I’ve found my place. My prospective landlord and I share much in common, and the apartment looks great. I would be renting a room from her and we would be sharing the apartment, including bathroom, living room, and kitchen.

We’ve had a gregarious email exchange tonight, and she wants to talk on the phone tomorrow. As has been revealed in my other recent questions on Fluther, I have no experience in such matters. Can you help me come up with a list of questions to ask her, or talking points that we should discuss before finalizing our agreement? The price is already fixed, so that is not what we’ll be talking about.

Merci d’avance :)
