C2 level English speaker giving private lessons

Hi, my name is Serafim. I am a trilingual student at UAM, studying psychology at the moment. Last year I've attained my C2 and finished writting my book (in English) which is why I want to give private English lessons to teens and adults in order to help them learn this beautiful language and encourage its further exploration. 
I can give lessons online for 10 euros/hour or if you live near Alcobendas I can teach at your place for 12 euros/hour. 
Don't hesitate to contact me for further details!
