Hi, Gema! I believe we can help each other. :-)
I would love to speak English more frequently, and part of my plan is to talk to non-native English speakers like yourself. In exchange, I would help you with any aspect of Portuguese. (Listening, writing and speaking).
I used to be a high school teacher (physics and math) and love to teach and chat.
Feel free to take a look at my profile and send me a message. It would be amazing to improve my English skills by learning more about Spain.
(I understand a bit o Spanish as well)
