Vague questions will only bring vague replies, like "San Juan de Los Terreros is nice" (I'm sure it is, by the way!)
"how did you get there?" What does this really mean? What is it you want to know (I'm guessing not which flights people took!)
"Any tips Re paper work etc" Have you found out anything about residency requirements, healthcare, employment etc. yet? There's mountains of information in previous threads here, but if you ask more specific questions you'll get more and better replies.
"will brexit affect this ?" Brexit hasn't happened yet, and at the moment the truth is nobody knows how it will affect things for Brits wishing to relocate to Spain. But yes, it almost certainly will affect things in some ways.
