If you are only going to Brussels and are considering spending, at the most, two or three hours in the other three cities, then this could be the guide for you, providing you don't require too much context. I was trying to decide on Antwerp or Ghent and got no help at all from this guide. After deciding on Ghent, I was even more disappointed - the guide is just very poor value, with hardly any information, no routes, no context. The same goes for the maps - the ones provided for the smaller cities are only small squares in the back of the Brussels map. Overall, there are much better guides to Belgium and I would not recommend buying this one.
