Spanish/English language exchange (Mexico City)

Hi all,
I am looking for someone to practise my Spanish hopefully once a week. I am at a basic/low intermediate level so am looking for someone who is patient while I learn to extend my use of vocabulary in conversation. I am already having lessons so am really looking for a 'practise' partner. In exchange, the other person can practise their English with me. I live in the Condesa area so it would be great to meet for coffee and chat. Anyone interested?
If you see this message and speak Spanish at my level and need to practise what you know, you may like to meet and just speak in Spanish the whole time. I am also open for this too. Just let me know.
Thanks,
Cathy
