Lisbon has become the happiest tourist city in the world. The Holiday Happiness Index ranked the Portuguese capital among 47 cities. Criteria: sun, healthy food, quality sleep and sports.

About 10% of establishments with healthy dishes are available in the city, which is the second indicator in the world. Tourists are not afraid to walk along the slope - sights are nearby, and panoramic views help to reduce the pulse. Plus there are green areas: per capita there are almost 50 square meters of grass, four times more than in Madrid.

The top 3 also included Helsinki and Orlando with Disneyland. Only one American city was in the top ten, the rest are European capitals like Athens and Edinburgh. It's nicer to live in these places.
