The only time I have taken a cheap high-speed train was an Avlo and the experience was very good. I only noticed the difference because the seats were a little narrower. I don't remember if they had a cafeteria waggon or self-service machines because I didn't need them, hehe. You got very good price for your tickets.
Yeah, it is basically the same, but more affordable 😉 and we can survive without a cup of coffee or tea served to us. Well, speaking about coffee, I will go and search for some now 😂
