Best Price Guarantee

We believe getting the language course you want for the lowest price in Amsterdam is possible. That’s why we have created our Best Price Guarantee, so you can always book your language course with confidence.

What is the Best Price Guarantee?

We guarantee you’re getting the lowest price. If you find a better hourly rate for an English group course, up to 11 people, face-to-face (on-site or online at a recognised language school), in Amsterdam, within 48 hours from your course registration, we will refund the difference of the hourly rate. 

Why MixTree Languages has the best prices in Amsterdam

MixTree Languages is a language school and a non profit cultural association that provides high quality language courses at an affordable price. We also organise social, artistic and educative events which our students and the public can take part in.

Being a non profit organisation means that we are not allowed to make any profit. In other words, we can assure that the course fees are spent only to cover the costs of the English course (teachers, space rental, materials, promotion and administration costs).

The advantage for the students is that MixTree can provide high quality language courses (We only work with highly qualified (minimum CELTA or TEFL) and experienced native English teachers) at an affordable price (including teaching materials and registration costs).


Distance and cleaning – COVID-19 guidelines of the RIVM

For our spacious classrooms, additional measures have been taken to help ensure the health, safety and well-being of our students and staff. We actively enforce the 1.5-metre rule and face masks when not seated in class.

Our classrooms have 2 entrances and are cleaned thoroughly before and after each group class. Hand sanitiser will also be provided in the building.

Live-Online C1 Advanced English Courses

In our Live-Online Advanced C1 course we use Zoom to create online classrooms. This program offers an excellent alternative to our in-person lessons. Our online lessons are as fun and interactive as our face-to-face courses.

I completed 3 programs on MixTree, A1, A2 and B1. My experience with the school is excellent.MixTree has outstanding, kind, and fun teachers. With a light and fun environment, they speeded up my integration and learning. They also constantly hold socializing meetings, which is great for practicing English and solidifying what we have learned. In a single year, I was able to substantially develop my skills, expand my vocabulary also make great friends.MixTree has definitely the best value for money when it comes to learning English in Amsterdam!

I did the Business English course. The teacher and course material were great. The course focused on interaction with other people. The course materials were provided, and they were really tailored to the course, I didn’t need to buy any books. I have done other courses. This one is the best by far! Highly recommended.It was a very nice sociable environment, a small restaurant next door, where also cultural events where organised. Made some new friends , and even met my girlfriend there 🙂

I had a 20-hour private course at MixTree Languages school. My teacher Liz was fantastic, after the first 5 lessons I feel much more confident during my conversations with friends and colleagues. At the beginning of the course I had a detailed program based on my level and my needs. My expectations have been largely achieved! Highly recommended!

I followed an excellent English course here. I was looking for a private lesson course at short term. MixTree Languages responded very quickly and arranged my schedule one day after my request. I enjoyed every lesson by my teacher Anastasia and she adapted the lessons perfectly to my needs. People were really kind and the atmosphere was very good and informal.

MixTree Languages English course was very useful. I was looking for an Intensive course that let me to be more self-confident to speak professional English for a job. I was also interested to get the correct English certification. All of this without spending a lot of money I suppose to have to. Thank you Mixtree and thank you Aaron to have suggested to me. Recommended!
