Marc's apartment was indeed lovely. Situated right next to the steps of the Sacre-Coeur Basilica, it was the perfect location for taking the metro around Paris. Everything was exactly as described, and clean! The concierge met us upon arrival and helped us get settled in. We had a fully-equipped kitchen, washer for laundry, bed space for 4 people, and lots of linens and towels. There was even an elevator for carrying up our luggage! I would definitely recommend staying here.
