My daughter and I are going to make a day trip from Paris and will arrive at Midi/Zuid mid morning. I wanted to visit Cantillon and I see that it doesn't look to far from the station, how is that area for walking around? How long would a walk from there to the Grand Place take? 10-15 minutes? We will depart sometime that evening and I also wanted to know if it would be okay to walk back to the station or should I take public transport. Thanks.
