Language Exchange.

I am living in Madrid and I need to learn Spanish as my level is extremely basic. I would like to exchange with somebody who needs to improve their English. Preferably intermediate or higher (as I know no Spanish). I have very limited availability either Tues/Thurs 16:00-17:00 or Fridays 12:00-14:00 (and this may change). I am located in Cuatro Caminos so would like to meet here (so people who live locally). Thank you and please do not contact me if you are not available for those hours as I am extremely busy with work!! Thanks and I look forward to hearing from you!
