Have you visited Peñafiel, Spain? I enjoy Spain, because each area seems it has its own unique character. Although I'm not much enthralled with Madrid, I would love to return to Spain other than Barcelona where I have visited quite often since 1991 - connected with cruises.
c.i, not to be a drag, but "Subte" is used for subway only in Argentina.
And "Congreso de Tucumán" is Argentinian.
Are you sure this is Barcelona, where the signs are also in Catalonian, and not Buenos Aires?
No, I want people to correct me when I'm wrong. I was going through some of my photos, and it looked like the picture I took in Barcelona. I've also been to Buenos Aires several times, but didn't remember any subway station there.
Please continue to correct me; I can get sloppy when I don't investigate what I post or don't have the detail of the photos I take (which runs into the thousands).
