With its hills and historic street cars, Lisbon can feel like the San Francisco of Europe. While it has the laid-back charm and mild weather of SF, the Portuguese capital is much older and cheaper.
The affordability stands out especially compared to other capital cities in Europe, like Paris or London. In Lisbon, the average Airbnb goes for $75 per night, according to the vacation rental platform. And you can eat and drink delicious Portuguese dishes, like fresh seafood or port wine, for great prices. A bottle of wine often hovers around $15 at an upscale restaurant, and you can enjoy an ice-cold beer for about $1 and change in one of the city's many outdoor kiosk cafes. The views are free.
