While Istanbul's 25% more affordable than it was in 2014, the Romanian capital, Bucharest, is the second-cheapest place for a vacation, costing Americans approx. $1,894 for a week of gawking at Art Nouveau buildings and museum-hopping, down 16% from last year. Krakow, Poland, is the third-best value, with a week’s vacay costing $1,983 -- though it's only 5% cheaper than last year, it's still worth visiting the city’s rustic Old Town and famous market square.
While other underrated European gems like Prague and Brussels make the top 10, big-name cities such as London and Paris fell to the bottom of the list. Because, well, they're always expensive. And as for the most expensive destination, to no one’s surprise, it’s Zurich: land of Swiss bank accounts, Bond-villain watches, and $7.50 Big Macs.
