The apartment was perfect. It is located facing a courtyard with peek-a-boo views of Sacre Cœur, the Opera and the rooftops of Paris. The apartment is incredibly quiet and well appointed. Everything you need is either in the apartment or can be picked up with a quick walk to stores. The Rue Vignon is a wonderful little street full of restaurants and shops. In my almost two months there, I never had an issue with safety or noise. In fact, I had hoped to stay there again in November but it has already been booked. I definitely recommend both the apartment and Christophe. It was a great experience all around.
