There currently is one option to travel by night bus from Barcelona (Spain) to Zurich (Switzerland), taking approximately 14 hours: Namely the 004BZ operated by Twiliner.
Twiliner is a bus company that redefines overnight travel by bus in Europe. The buses feature special seats that can be transformed into beds at the touch of a button. The vehicles are equipped with spacious toilets, changing rooms and a snack bar and run on HVO diesel for reduced emissions.
Twiliner's patent-pending seats can be fully reclined into a bed at the touch of a button. According to the company, they are the first of their kind in Europe. The seats feature a safety system that enables travel in different positions.
The buses offer free Wi-Fi and power outlets at every seat. In the lower deck there is a toilet, changing room and snack bar with various drinks and snacks. Each seat has its own storage, a work table, USB ports and reading light. Water, coffee and internet are provided at no extra cost.
Per person, Twiliner includes one suitcase (maximum 23 kg) and one carry-on item (maximum 5 kg). These are transported in the luggage compartment. At the seat itself there is only space for small bags or backpacks. Additional luggage incurs charges.
