This apartment was very well appointed, clean and in a great location. It was close to the metro and a walking distance (15 to 20 minutes) from Notre Dame. It was perfect for my husband, myself and our daughter. The apartment is small, but provided everything we needed. Marie was accessible by email. We did not meet her. There was a little mix up with the initial access to the apartment. If you rent, please make sure that you print out all her instructions - including the address, which is different from what was listed on the Itinerary.
All in all - we had a wonderful time and this apartment was a great jumping off point for all our Paris adventures! I would definitely stay here again.
