Looking for Host Family: Language Exchange/Immersion

I'm a young male student coming to Spain in October to study an MBA in Sports Management in Universidad Europea: Alcobendas. I am a native english speaker looking for accommodation in exchange for English immersion. If you have children, I can play with them and educate them in English for 1-2 hours a day. It would be great if you could accept me into your home! :) Looking for an exchange that lasts a minimum of 3-4 months.
