Nathalie was in touch with us both before and during our stay. She was very welcoming and should we have had any issues she was amenable to helping us out. The apartment was exactly as described and perfect for our family of 5. It was very hot the weekend we were there but there were plenty of fans to cool the apartment. There were a lot of stairs so I would definitely recommend bringing smaller suitcases. However we were aware of that before so it wasn't a problem. We loves the views out of the windows onto the courtyards and the street it was on is so authentic with bakery, cheese store, wine store and other little boutiques and restaurants. We really felt like we were living like Parisians! The location was fantastic, so close to Notre Dame, the river and the metro. Yet not noisy at night. Would recommend definitely!
