Spanish language course

We're looking for an Erasmus student speaking native Spanish to practice Spanish once or twice in a week with my  son. We had lived in Madrid between 2010 and 2012. My daughter speaks Spanish fluently but my son started to forget. For that reason, he needs to review grammar and make practise. He is 11 years old and educating in secondary school. We may arrange time for the lessons in weekends. If you deal with our offer, please call us.
