Marie's location and place is awesome! Her place is two blocks away from the train station and the neighbourhood is very likely and safe. I felt like I was in Soho in New York. There are falafel places and cafes close by if you stay out late at night. Her apt is very nice, comfortable and has great air circulation, despite the heat I experienced while walking around Paris. I didn't see Marie when I arrived but she left detailed instructions and recommendations of places to eat. She also left maps and lonely planet guides to Paris!
