We spent 4 dais on the road to cross Europe from Serbia to Portugal by bus, because it was the cheapest way to make this trip.
For those interested, we bought our bus tickets from Flixbus (https://www.flixbus.pt/). Flixbus really worth it, as it has lots of discounts and promotions.
We made the video below for you to have a glimpse on how such a trip is like. Have a look. It’s pretty funny.
