London is the dirtiest and most expensive city in Europe, while Brussels is the most boring, according to a British survey published on Wednesday.

London edged out Paris for the unwanted accolade of dirtiest city in the survey of more than 1,100 travellers carried out by TripAdvisor.

Respondents said Paris was the most unfriendly, followed by London and Moscow, but the French capital is still working its old magic as it was voted the most romantic destination in Europe and the best for shopping and dining.

London won out for having the best nightlife and public parks.

The cleanest city is Zurich, the survey said, although the tidy Swiss city also finished equal second behind EU hub Brussels as the most boring place.

Prague was elected the best bargain city, followed by Budapest and Lisbon.

Despite the weak dollar, half of the Americans surveyed said they planned to visit Europe this year, the same number as last year.
