Definitely a huge help in learning Dutch ! I really like the fact that she has a clear method and good materials to recommend and follow which I found very effective for a complete beginner. I found her explanations really good and that`s great considering the "nice" grammar of the dutch language which is not that bad after some effort and good guidance :) She is also very serious regarding timing, never late and if a change in hour or day appears she always gave a long notice and we were able to adapt. Other good things I would highlight about Tess are a very enthusiastic attitude, a funny person and good at conversations. These characteristics make the lessons enjoyable and have a nice flow. Nothing negative until now.
