We spent a whole month living as a family of 5 in the duplex and had a wonderful time.
The apartment is cosy and functional, the courtyard is very secure and surprisingly quiet in the center of the city.
The location is excellent, close to public transportation and everything you need is right nearby. The biggest bonus is the "Marché d'Aligre" two minutes away where you can buy the best quality meats, fish, produce and cheeses. And since the apartment has an equipped kitchen, you can cook French dinner at home without eating out daily. There are also many bakeries (boulangeries) in the neighborhood, the one across the street has the best croissants and the one around the corner the best bread. After a month is was like leaving Paradise...
Penelope is very nice and responsive, she lives nearby and really cared that everything was well and whether we needed anything.
