Exchange- native teachers

Hello, I am an English teacher. I teach at 2 different academies here in Barcelona. I would like to have a Spanish teacher as well that would be willing to meet once a week. One hour of me teaching English to you, and one hour of you teaching Spanish to me. I need more than just conversation. 

We can meet at your home or mine. Whatever you prefer— due to prices of classes it would be nice to have a free teacher exchange :)
