ES is a very poor country with a sordid past but the people have been really friendly and helpful. Met some very kind and interesting people so far. The countryside is much more beautiful than I expected, and the cities have some very old infrastructure, but there is lots of construction going on and things seem to be improving rapidly. Bitcoin adoption is also growing but not accepted everywhere just yet. My Spanish is terrible but I am learning. So brush up before you go (if needed) and as long as you try you'll be fine.
