Nicholas is the best knd of Airbnb host. He made everything really easy, even carrying my suitcase up the stairs for me! He left us a baguette, jam, cold water, juice and a baguette for our first breakfast! The apartment is adorable and a perfect pied-a-terre in a wonderful neighborhood. If you are staying in Montmartre then climbing hills is probably not a big deal for you; even with a recent knee injury I was able to climb the stairs just fine. It was hot when we were in Paris, but between the window, the skylights and two fans in the apartment we were very comfortable!
