My second trip to Europe was to one of the most multicultural cities I have ever visited, its modern atmosphere but with a classic touch makes you fall in love with its streets, buildings and squares. You can take day tours of the city, which leave from the GRAND PLACE in specific groups in different languages and are completely free, of course you can thank your guide with a significant tip.
The location of Brussels makes it ideal to include it in your travel plan between France and Holland, since it is super cheap to travel by bus and thanks to the proximity between the 3 countries, you can visit the important cities in 1 week.
