As the worst student ever, I would like to add an opinion after almost 30 classes. So, after about 5 classes I started to treat Nico as a friend. We can talk about everything, and I feel free to talk about my life. This is what I needed because I started speaking about normal things in Spanish, not school things. Before lessons with Nico, I participated in classes at a Polish language school, and I think that I made bigger progress in 9 months with Nico than in 1,5 years at school. I would highly recommend classes with him, he was my first choice and the best choice. For all those people who are scared of having classes with a native speaker, try it, and believe me that is the best experience ever ;) But wait, there is something more! He creates very interesting podcasts which you can listen to on Spotify, and practice Spanish in your free time. So, don't hesitate to have lessons with him.
