Hello! After all, all went quite well. The checkin was easy, but a bit strange to move to another person on wh*ts*pp for such easy checkin. The first impression was: ooh, this is not a lively area and there is a strange dusty smell. But finally we could take a train at Santa Apolonia for a conference we attended which was actually very convenient. And we took Ubers to get to lively areas more in the centre when needed. At the end we had a pleasant stay.
