WTF Montpellier T.T ? Did you really saw Noailles and Calanques ? T.T The weird mix between the poor Newborough that have drug dealer, just right next to the rich neighbourough just living in front of a hiking spot on mountain, with drug dealer having loyalty card, and Olympique de Marseille being raise at a level of a religion where the Velodrome is a temple (It's so high I suspect Mulsim Marseillan to go more to the Velodrome than at the Mosque), with hills everywhere on the city, and you systematically go up and down. To me they are a lot of things that makes the city unique (Calanques specifically, weird culture too)
This humorist have made a good summup https://www.youtube.com/watch?v=_JSMej2gB80
Wish part did you visit ? Only the "Vieux port" and the "Cafetière" ? (Thats the only part that couls be seen as Montpellier to me)
