CONVERSATION EXCHANGE AT LUNCH BREAK METRO BEGOÑA

Hi there!
I'm looking for a native English speaker to help me to improve my speaking. I'm a former Spanish teacher so I can teach you properly. 
I would like to use my  break for the exchange so I'm looking for someone who can meet at Begoña tube area,line 10( where the 4 towers are located).
Drop me a line if you are interested, please! :-)
