If one asks Romanians plenty of them, will vote for Cluj as most overrated city. Especially because of the housing prices. And then maybe Sibiu, Constanța and so on. Sibiu, because except for the historical center there is not that much too see.
In most cities just the center looks nice/ better. The periphery is sort of dull.
We also used to have a natural waterfall called Bigăr (read as the English word "bigger") cascade. In 2013, the international specialized press named it as the most beautiful waterfall in the world. In reality it was kind of small and overrated compared to the photos and the place was crowded with tourists. If eventually partially collapsed and the joke is, that now its name should be changed to "Smalăr/smaller waterfall"
