This was a perfect apartment and location for our small family.
We purchased 3-day passes for the botanical gardens on the first day (25 euro/adult and 15/child) and visited the zoo, mineral exhibit, natural history museum, special ocean exhibit and greenhouses. Perfect for entertaining our 7 year old and very close to the apartment.
It is also very close to the Batobus River stop - we purchased 2-day passes (19 euro/adult and less for children) and used it many times.
Comfortable walking distance to the Catacombs, Luxembourg gardens, and Notre Dame area. We also walked to the Marche Oiseau - another recommend activity for those with children.
The apartment had everything we needed. We cooked a few simple meals and made our morning coffee at home. Small grocery is across the street.
