The location is very convenient from a public transportation perspective -- easy walk to either the 65 or 66 buses (two different routes) to Central Station, which is a half hour ride with buses every 10 minutes and timings listed on a digital display at the bus stops. Also very close to tram station that can take you either in the direction of the airport or the Gare du Midi (number 62 and 3 tram lines, which we had to go to in order to get our train to Germany). There is a full Carrefour supermarket right across the street with a buffet restaurant that has free wifi so shopping is convenient.
The apartment was wonderfully warm in the cold winter and it had a nice big bathtub which was great for coming home with a toddler after a long day in the cold. Washing machine made it super convenient when travelling with a toddler.
The apartment is spacious with big window all around on 7th floor showing a panorama of the city -- you can see the Atomium in the distance from one side.
