Italy’s financial capital recorded 9.9 million overnight stays last year, a jump of 8.3 percent on 2012, making it the second-fastest growing tourism city in Europe behind Hamburg in Germany.
Milan is the 14th most popular destination for travellers, ahead of Dublin and just behind Stockholm, according to the study by European Cities Marketing (ECM) published on Thursday.
But Rome remained far ahead of the northern Italian city, ranking the fourth-most popular tourist city in Europe.
There were 24.2 million overnight stays in Rome in 2013, an increase of 6.2 percent, trailing just behind Berlin which boasted 26.9 million last year.
London remained the most popular destination of 115 cities on the continent, with visitor stays increasing by 3.3 percent in 2013. Paris clung onto second place but visitor numbers declined by 0.6 percent on the previous year, ECM said.
Across Italy, the country attracted 46.4 million overnight visitors from abroad, a steady increase in recent years, World Bank data shows.
Italians are also keen to travel in their own country. More than three quarters choose to holiday within Italy, EU statistics agency Eurostat said last month. More than a third of Italians shun foreign trips entirely, only going on domestic trips, a trend also seen in France and Spain.
