When you imagine the French capital, you imagine impressive monuments, romantic cafés and pretty parks... but the truth is, real Paris clashes with postcard Paris.

Paris authorities pump a lot of money and manpower into keeping the city clean. So what’s the problem? Could it be Parisians themselves?
