I recently stayed for 4 nights at Marie's place and loved it. I couldn't have found a better place for my short visit in Paris. The aparment is located in the backyard of an old building, right in Paris' heart. There are old cafés, boulangeries and famous falafel restaurants just at your doorstep. It's only 10 min walk to Notre Dame, and 5 min to Pompidou Art Centre. The aparment is small but has everything I needed. You can choose to sleep either on the sofa or on a matress on the floor behind the sofa. I slept on the floor and it was a very comfortable bed! Marie is a very nice and helpful person. I met Marie on my arrival, late in the evening and spent only a short time with her. She gave me plenty of useful information. I appreciated her insider-tips about where to eat, where to go and was thankful for the information about how to get from & to the aiport (there was a transportation strike during my stay). I can highly recommend to stay at Marie's place, especially for women travelling alone, this is the perfect place!
