The flat (maybe too tiny for 4 people, but ok for a family) is very practical (at the ground floor of a quiet backyard) and convenient to visit Paris: 10 min by foot from the tower and very closed to metro lines. Around you can find whatever you need: supermarkets, bakery, pharmacy, cafes and restaurants...
Taoufik is very kind and helpful for any info you need.
Very good "value for money" solution.
