The overnight trainhotel (trenhotel) between Paris and Barcelona is the easiest way to travel between the two cities by train. The journey is made on board a rolling hotel, the Joan Miro run by Elipsos.
There are four principal seating options, with the most uncomfortable (for an overnight journey) being a standard reclining seat. Often the cheapest option is to travel in Tourist Class, which is a four-berth cabin with washbasin. Preferente cabins have one or two berths, with a washbasin and breakfast included. The most luxurious class is the Gran Clase, which has one or two berths, a private shower, toilet, and includes breakfast and dinner in the price.
