Incredible, beautiful and warm country.
If you want to improve your English, and also actively spend time, then your choice is the EF school in Malta. I heard different opinions about the training in EF Malta (and you understand that they are not always positive, since there are so many people and opinions), but, having visited this school, I remained in incredible delight.
Organization of the whole program was at high level. The school itself employs teachers from different countries and with different accents, which I really enjoyed. Classes were interesting. I learned a lot of things.
I lived in a host family and my Maltese mum and dad were incredibly open, kind and attentive to me. There were no special rules in the family, only, there was a certain time for dinner, but it's ok. Over dinner we always talked like a real family, like how shows in the cinema, and I talked about how my day went by in the school, in the city. It was soooooooooo cute! :)
Also, I found a lot of new friends from different countries. It is incredibly interesting to learn the culture of other countries for me.
The beauty of Malta can not be expressed in words. You should to see it in person :)
As a result: an ocean of emotions, I improved English and have a life long memories.
