在Tripadvisor上有答案，节录如下：

The lockers at the bus station are now 4 euros. They are rather large.There are also lockers at the train station. There are three sizes and cost 3, 5 or 6 euros. There is a security guard at the entrance of the room. It is located at the far end of the station. There are signs pointing to it, you can't miss.

刚给你查了Adif官网，该火车站提供的服务里没有行李寄存。

楼下说的是汽车站，有可能信息还是有用的。西班牙通常都是火车站无寄存服务，汽车站有。马德里除外，首都嘛。

火车站的行李柜已经取消了，没有人工存行李的。火车站对面的的汽车站（穿过马路）有行李自动存贮柜，但是尺寸不大，如果你的行李太大的话，不一定能放得下。一定28“以下的都能放下。
