The review of 48 destinations by Post Office Travel Money found the cost of a city break can vary hugely - from under €170 to more than €500.


Costs in some popular destinations have tumbled over the past year - including in Venice, Rome, Amsterdam, Madrid, Lisbon and Berlin.


A getaway in the Portuguese capital is currently €238, down 1.4 percent on last year. Porto in Portugal was also among the cheapest destinations in the research, priced similarly to Lisbon.


A cheaper and wider choice of accommodation has helped push down prices, the report said.
