We had a great time! True to the description, the views are terrific, like something out of a children’s story book. Our two yr old spent many hours playing on the terrace and probably would have been content playing there for the entire trip. It was really refreshing to eat al fresco on the terrace. The apt was very clean, had a well equipped kitchen, and had plenty of towels/blankets. Location is really great, couple of minutes to the metro, a block away from the base of Sacre Coeur, and best of all close to many yummu bakeries and various food purveyors. The building and location was also very quiet. If you have heavy luggage, would recommend taking a taxi to and from the airport which takes about 30min (we paid flat €45 via Uber). However if light packer, taking a train is straight forward. You simply hop on RER B train to Gare du Nord (€9.75 per person) and take M4 subway one stop to Barbes-Rochechouart. Martine was a great host and very friendly. Our taxi was late and she offered to drive us to the train station if need be. She even offered us to stay with her if we missed our plane.
