Marc is a great host! He was flexible with the check-in time around our schedule when we were arriving to Paris. He even stayed around after letting us in to show us the apartment, how to lock up, and some maps that overviewed the area.
The apartment is beautiful overall, and we were sad that it was rainy and we weren't able to use the awesome terrace more often! His location is great, being close to two metro stops that can take you around Paris with ease and a short 15 min walk to the Lourve, Notre Dame, awesome boutiques and more. 10/10 would recommend and stay again!
