I heard of companies in South America that travel by night and offer beds in the bus. A friend, recently in Colombia, used them and refered to that as "very good service, the buses are very high quality and you get to the destination like you you never left the same place. And you have a full day ahead of you to visit a city".
I know he is an "easy sleeper" but anyway, I believe it's confortable enough and definitly very convenient to travel between distant points, saving time and money. You also save yourself from the complexities of airports. I know there is the same in Europe with trains, but I was wondering if such a service exists on a Bus.
Are there night bus companies, providing beds on board, in Europe?
