There is a large reconstruction, there are almost no shops, a burger king with a toilet is conveniently located, about 10-15 minutes from the train station for SIM cards. There is a jamb on trains to the airport: after the platform number appears on the scoreboard, you have 3!! minutes to get there- the train leaves, the station is passable, so wait in the transition at a low start. From the pros: you will get to the airport for free if you have already traveled by train to Madrid)
A terrible train station, there are always a lot of people, until the last it is not clear which platform the train will come to, there are no conditions, there are no benches to sit down, everyone is sitting on the floor in the crowd, they almost walk over their heads ((((there are only two places to eat, where there are giant queues and infernal prices((((
