Mainstream medias??
I am living in the capital of the EU and making use of that since I am working left and right in Europe for now quite some time.
Yes, there are better cities than Brussels in the world but not many where I would like to live and work (job opportunities thanks to the EU, international airport easily reachable, plenty of diverse restaurants, efficient public transportation, not feeling insecure, plenty of museums, all the shops needed, balance between cost of living and quality of life, opportunity to continue using my skills including language thanks to +35% of foreigners in Brussels, centrally located, which allows quick travels to every corner of Europe when your company is sending you there).
To quote someone:
"You go to Brussels — I was in Brussels a long time ago, 20 years ago, so beautiful, everything is so beautiful — it's like living in a hellhole right now,"
Which is funny considering that 20 years ago some areas of Brussels were really close to that hellhole description while these days things get better.
Mind you, trump's opinion is shared by quite a few Belgians (Flemish side) who either never dared go to Brussels or just go there to work.
