I spent two week at The λamda Project doing a 30 hours/week intensive course in modern Greek. The programs are very flexible and adaptable to individual skills and needs. The teachers are highly educated people with very good pedagogical skills - who teaches with great enthusiasm and energy.
The provided working book is tailored for everyday situations at different levels, facilitates interaction, and gives a systematic and gradual approach to grammar - perfect for the small size class model.
Private/ individual sessions were also very good and professional.
Very modern and suitable facilities with bakeries and many charming restaurants in pedestrian streets close by.
The staff are very service minded, friendly and including people - felt like a home with very good energy. They also arranged trips, guided city tours, Greek dancing lesson, trip to museum.
I made good progress during the stay, and plan to come back for another session later.
It is quality all the way through - I highly recommend this place for learning Greek in Athens!!
