Vienna has the best living standard in the world - and Baghdad the worst, according to an annual survey.
Mercer consulting group also gave German and Swiss cities top rankings, putting four of them among the first five, and says European cities represent over half of the top 25 municipalities graded.
The Austrian capital regularly ranks high in such surveys.
Although it is rising, the crime rate in Vienna is still among the lowest in Europe. Public transport and other services are excellent, and streets are clean.
Zurich was ranked second, followed by Auckland and Munich and Dusseldorf.
Dublin was 26th and London 38th.
"European cities in general continue to have high standards of living, because they enjoy advanced and modern city infrastructures combined with high-class medical, recreational and leisure facilities," said a Mercer spokesman.
But he cautioned that could change as the continent grapples with its financial crisis.
"Economic turmoil, high levels of unemployment and lack of confidence in political institutions make their future positions hard to predict," he said.
