Spanish guy looking for an intercambio partner

Hi, My name is Juan and I'm 27. I've been living in Madrid for a year now and would be really interested in finding someone to practise my English with. Needless to say, I would help you with your Spanish too; I always try to be as patient and helpful as I can! I'd like the idea of meeting in the centre and going for a coffee or a beer! if you are a nice person and you'd like to meet up, just let me know  :)
