Francois was wonderful. He speaks good English, knows his history and is a good story teller. We met him at the Grand Place. It was a cold and rainy day but he made it a very pleasant outing. The tour took about two and a half hours with a stop midway at a church. We were able to use the restrooms at an adjacent coffee shop.
Of course, the tour is not free. Francois has to have shelter, food, etc. Tip guidance is between ten to 30 Euro per person. We gave him US $20 per person. So glad that we did the guided tour.
