for us ( a couple with an infant) this place was too good, although it's in the suburbs of Brussels (30-40 mins to the center using public transport). But really nice nature scenes and park near by(there is even a garden in the house! :) ).
We stayed for 2 days and our baby had a bad case of colic pain and wasn't quite at all, but no complains from the owner at all.
Therefore, I really recommend this place for small families.
