First day at my English school in London

Hi
I'm very sorry if you have missed me :) .
I'm here in London and fortunately it's available a wifi connection so I can keep you posted as it's possible. I wanted to write some notes down before my departure but I ran out of time.
Today I took my English placement at Mayfair school, it was not bad at all and I have to attend an English course in the morning (9-12) from Monday to Friday plus other lessons in the afternoon (I chose a semi intense course).
I haven't had time to horse around London, I saw only Oxford street.
Here I'm guest of a host family, they are very welcoming and friendly.
I'm dead tired.. I go sleeping.
