The analysis by Bounce, analysed several parameters, including the number of stations, Google reviews, and the number of passengers to evaluate the metro systems in several European capitals.

“Metro systems in European capitals are essential for navigating these historic cities, but the quality and accessibility of the facilities vary,” reads a statement released by Bounce, which gives the example of the Paris metro in France, which is criticised for not having adequate facilities for people with reduced mobility.

In Bounce's assessment, the Lisbon Metro was ranked seventh, with an overall rating of 5.97 points, the same rating achieved by the metro systems of Copenhagen, Denmark, and Bucharest, Romania.

The Lisbon Metro, which has a total of 56 stations, recorded 15% positive ratings but 22% negative ratings, and is the one with the highest score in this parameter within the Top 10, while Google's rating is 4.09 points.

The ranking presented by Bounce is led by the Oslo metro in Norway, which obtained an overall rating of 8.06 points, followed by the Sofia metro in Bulgaria, with a rating of 7.64 points. The Top 3 is completed by the Athens metro, with a rating of 7.29 points.

Also in the Top 10 of this ranking are the metros of Madrid (6.74 points), Warsaw (6.60 points), and London (6.04), with the Prague metro closing the list, with a rating of 5.83 points.
