Spanish PhD victim

I am 26 years old, from Madrid (Spain). I am currently in my last year of my Ph.D. in Neuroscience.
I am very easy-going, flexible, and open-minded. Like to teach with a good funny and/or interesting conversation. I believe this is the best way to learn a language: to feel in a friendly environment where you are not afraid of trying and trying and trying.
I have helped international people with Spanish before and always had a good experience. It's really easy to learn as long as you practice conversation, which we will mainly do. We can either meet at a bar, cafe, apartment, etc. All levels are welcomed :)
