Hi dear, unfortunately the sentence is not in spanish -actually, I dont know what language it is, it has some spanish elements but with other languages and english. I dont understand the sentence because it seems to be translated with an online translator. Could you put the sentence in its original language, which I assume is english?

Trabajaré en este cuadro/red/rejilla (it depends of the context)

At first I didnt understand what you wanted to say, but then I understood that you want to download all che guevera's books. In that case, you should have said: "¿Alguien sabe donde puedo encontrar los 18 libros de Che Guevera en pdf? - Estoy interesada en conocer un poco más sobre el Che". Anyway, in THIS link: http://historiaybiografias.com/libros_che.zip you can find all the books. It is a zip file and it has all the books!

I think Madrid and Barcelona are excellent options.

Hi! "a tiro" means near or close to something It was very difficult for me to find a meaning for "A la vasca", because I'm not from Spain and apparantly only they use that word. I think "a la vasca" means a way of cooking something (for example, fried or crispy chicken), I'm not completely sure but I think "a la vasca" is when something, for example chicken, fish, ect, is cooked with coriander. It is related to País Vasco (part of spain) "a favor" means "in favor of..." or "agree with". for example: estoy a favor de de esta decisión -> I agree with this decission.
