Learning English/Spanish by sharing experiences & interests

I would like to find someone to practice English and help with Spanish. I am a native Spanish boy doing the PhD here in Madrid. I lived in California last year and would like to keep practising my English here in Madrid with a good English speaker/native person. My level is around C1. I would like to find someone who shares same interests as me, as they are nature, music, films, theatre, travelling, animals, food, walking or having a beer while discovering new places in this city. Actually I am working with plants stuff so somebody really into nature will be great!
