In a recent global assessment compiled by Radical Storage, a luggage-storage network, Hyderabad was ranked 18th among the world’s 20 dirtiest cities based on tourist reviews. Surprisingly, Hyderabad was the only Indian city featured in either the clean or dirty lists.
The rankings were based on an analysis of cities which were listed in Euromonitor’s Top 100 City Destinations Index— a yearly index that scores destinations on various metrics, including tourism performance, travel sustainability, infrastructure, and visitor appeal.
Radical Storage conducted an extensive exercise by analysing Google reviews for the top 10 attractions in each city between October 2024 and November 2025. Reviews were scanned for words like ‘clean’ and ‘dirty’ and then categorised as positive or negative depending on the context to assign a final "cleanliness score" to each city.
In the 633 reviews analysed from Hyderabad, 16.1 per cent of tourists made negative remarks regarding the city's cleanliness.
The resulting list saw Budapest emerge at the top as the dirtiest city overall. The worst-performing cities after Budapest are Rome, Las Vegas, Florence, and Paris.
Conversely, the cleanest cities in the ranking are, namely, Krakow (Poland), Sharjah, Singapore, Warsaw and Doha.
