That sounds a good idea to living in Spain. Spain is really a beautiful country in the world to visit. I spent several days in Barcelona and Madrid, and I'd like to go back again for awhile. I think if you're in Barcelona be sure to check out the Picasso museum as well. And I deem that the best way to get around Spain is by train and you can enjoy the beautiful landscape along the way. Finally I can recommend you some property sites I have come across, palmas real estate and lake tahoe hotel. Hoping these could give you some help!
Good luck!
