Sebastian is a wonderful teacher. I met him in 2015 when he was an English language assistant in Ibiza, Spain. I was traveling there for vacation and I could barely speak any English when we first met. We got along very well and he gave me English lessons while I was there. I liked him and classes so much that I continued to have skype classes with him after I left Ibiza for the next three years. Now I´m fluent in Engllish!
