Out family of four(including 1 and 5 year olds) spent 4 nights here right before christmas. The apartment was very clean, warm and well decorated. Baby kit(high chair and crib) was a big plus for us and no issues walking around with a stroller (elevator and parking lots all well connected). All the amenities you might need were well prepared.
Tips for families with young kids: it is worth to check out a big toy store in 10min walking distance(B**j*).
Definitely recommend this place for visiting Quebec!
