For me it was worth it. I arrived over 9 years ago with no spanish, no where to live, no skills or vocation and knowing no-one. Im now in Madrid working as a freelance graphic designer w?th my partner and our baby girl 2 cats and noisy neighbours. I wouldn’t ever go back to blighty, Spain has been way too good to me. Yes the paper work can be pretty horrendous but theres always someone who can help you. You’ll get probably get sent from pilar to post by several different government workers but you’ll get there in the end. Its all about your attitude. Good luck and let us know!
Another thing, try and get as much spanish under your belt as you can before you arrive. Im intrigued to know what this summer business idea is…
