Dublin has been voted one of the friendliest cities on the planet by an influential travel magazine.

Readers of Conde Nast Traveller ranked the capital fifth in its top ten of the world's most welcoming urban destinations.

Rising eight places from the 13th most friendly city last year, it shares the position in the popularity stakes with Sydney, Australia.

The top spots included Auckland, New Zealand; Melbourne, Australia; Victoria, Canada; and Charleston in US state of South Carolina.

Only two European cities made it into the top ten - the other being Seville in Spain - compiled from the findings of the magazine's readers choice survey.

Dublin is described as a "vibrant city" and, in a nod to its literary fame, as a "bibliophile's dream".

It was also noted for being "green, lush and very walkable" and "the kind of place you stop in for a drink in a local pub, only to end up chatting with the locals for the next five hours".

The magazine also references US First Lady Michelle Obama's trip to Dublin with her daughters last year when she was photographed with Bono at his local pub.

Tourism Ireland Chief Executive Niall Gibbons said the city's high ranking came as no surprise.

"Again and again, our research shows us that the friendliness of our people is one of our unique selling points," he said.

"It is the warm welcome and the 'craic' here that resonates with our overseas visitors and makes Dublin and Ireland such a great choice for a short break or holiday."

Other cities making up the most friendly list are Siem Reap, Cambodia; Cape Town, South Africa; Savannah, Georgia; and finally Seville.

The poll also named the most unfriendly cities in the world as Johannesburg, South Africa; Cannes, France; Moscow, Russia; as well as Paris and Marseille, also in France.

The worst ten also included Beijing, China; Frankfurt, Germany; Milan, Italy; Monte Carlo, Monaco; and Nassau, Bahamas.
