A Polish travel blogger, Karosolotravel, has sparked controversy by describing Bologna, Italy, as the "most disgusting city," citing extreme dirtiness, neglect, and a pervasive urine odor. She visited in autumn 2025 and reported feeling ill, leading to an early departure, regretting not choosing Verona or Florence instead. While her Instagram following is small, a TikTok video detailing her negative experience went viral, garnering over 400,000 views. Her criticism has resonated with some locals and a local politician who agree with her assessment of the city's decline. However, the majority of online reactions, particularly on social media, strongly oppose her views, with many defending Bologna and suggesting other cities are worse. This incident follows a 2024 New York Times article that also labeled Bologna a "tourist hell."
