We recently had the misfortune to book Superior First class on the Sud Express from Lisbon Oriente to Hendaye. Having read that it was akin to the Orient express we decided to treat ourselves as according to the literature that we had read it include dinner and breakfast on the train and a steward to make up the beds and return them to seating.
We boarded a very old and dirty train, with no restaurant car, no breakfast included and no steward. The staff were very surly and unhelpful and where they got the idea that it was an Express I don't know, it stopped many times, was very rattly and noisy making it difficult to get any sleep. When we arrived in Hendaye it is a very old tatty station with no lifts, escalators or porters so it all had to be taken up and down stairs by hand and at 76 years of age it was no joke.
So my advice if you are planning this trip is DON'T !!!!!!!
