Hey... so I have a question to you

Is here anyone from Wales or UK, especially from London or Cardiff?

Because in three weeks I will go one week to Cardiff and one day to London. In Cardiff I will live by a other family, but I want to ask if anyone can recommend some things... I have only one day in London and I want to see many things... but I have no idea what. Yeah, sure the known sights, but is there something I have to sea??

The best would be, if I can meet there a person how live there and that person can show me and a friend from me the city. But I know that is difficult! But I can dream of it^^

So if anyone live in London I would aks him or her, for some tips.
I hope so that anyone will write me... so please!! I want to talk to you!^^
