We had a very nice stay in the apartment of Song. We traveled as a family with 3 adults and 2 children and the apartment was big enough to allow privacy for all.
As the apartment is located on the ninth floor it is very bright and shiny which is beautiful. As we had perfect weather during our stay we used the balcony for breakfast.
The area itself is very convenient: you find bakeries, supermarkets, a cheese shop and some bars and restaurants in less than 5 minutes walking distance. There is also a daily market a couple of minutes walk away.
The nearest metro station is just outside the building, but there or other lines within walking distance of less than 10 minutes.
We liked the area as you feel of being part of Paris where people live and work and only little tourist around. We definitely recommend the apartment of Song and would be happy to return.
