Quite unexpectedly, a free Monday and Tuesday appeared, and tickets to it cost 80 euros per retour. So it was decided to go to Barcelona for a long weekend. Since it was the eighth trip in a year to "have a rest", the budget was somewhat limited, and I don't like minus on a credit card.
There are many stories about the pen, so I will not repeat it. What I do not advise you to do: travel by bus, although it is cheap, it takes a lot of time and unforeseen excesses are possible.
