Room in Exchange for Homestay with Family

I am and English teacher from America and am travelling to Spain to teach English and to learn Spanish. I am hoping to find a family to host me in exchange for conversational English exchange each week. Ideally, I too would like to practice my Spanish some while living with the family. I have experience teaching both children and adults and have now been teaching English as a second language for almost ten years. :) Ideally I will stay with my host family for three months from the middle of December until the middle of March.
