I spent the last two weeks at CreteLing Summer School and I recommend it to everyone.
The teachers are prepared and ready to answer any questions, both during lessons and in their free time. Students can present posters of their work and two very interesting workshops with internationally renowned professors are planned. Furthermore, the Summer School organizes evenings with games for students and dinners to spend an evening in the company of students and/or teachers.
Rethymno is a beautiful seaside town. There you can eat excellent Greek food and you can spend your free time at the beach or walk through the vibrant streets of the city.
Overall, I wholeheartedly recommend this experience. Erasmus + has made my wish come true.
