London, a dream come true

In July I will go to London, because they have given me a Erasmus scholarship. 

I've been learning more English since the month of September.

In London I will live with a family, I will do business practices for one month. I have never visited London.
If someone wants to give me advice about London and the nicest places to visit, I would be very grateful.

For example typical food, summer time, how people live in London, as getting around town etc.

Thanks :)

I've never been there, congratulations on your scholarship!
