When I put a foot in the school for the first time, the thing that I will never forget is a big smile coming from the people of the reception. This is the kind of things that means a lot to you when you are feeling like a strange person in a country that you have never been, as it was in my case.

In the classes, I don’t know if I’m a lucky person, but the teachers that I have had, in my opinion, are excellent, very professional in their jobs, and they just seem to enjoy teaching, and make the lessons useful and classes amusing.

Another fact that I’ve really enjoyed is that the school is not only aimed at the English language knowledge. You can also find every kind of activity intended to entertain the students in their free time, with things like going to museums and galleries, visiting special places in the city or going to the very famous pub night to have a few beers with your friends. So here you have the opportunity to enjoy the stay in London, to meet new friends, and also to learn everything about the city and the British culture.

Personally, there are some facts that have not been easy for me since I arrived, like being so far away from my family, the differences between English food and the food I used to eat, and the high prices for everything. However, I am impressed about a very developed and multicultural city, with people aware of the sense of living in community, with a public transport amazingly thorough, with outstanding tourist places, with opportunities for work and with food from every part of the world that you can imagine.

I’ve experienced something priceless with my friends in London. Every time I made contact with my friends from another country, I learn about their culture. I was lucky to have such good friends. I think that time was a present for me.
