I love travelling and travel a lot but I rarely go anywhere and think OMG that was total crap. You can usually find positives and learning experiences anywhere. That's said, I think the only place I truly hated was Vienna. I did go in 1997 though lol. I must have been shit as I did a European backpacking trip, visited many places and still remember it from all those years ago! haha Big city, no heart and soul, incredibly rude and unhelpful civil servants. It might have changed since then. I did go to Montpellier last year and I wasn't super impressed. Extremely busy to drive around, really stressful trying to get parking around the beach areas - probably won't go back there in a hurry.
