Next Sunday I´m will be arriving to  at  Stanted airport at seven o´clock in the evening. It´s going to be my first time in London. I´m very happy with this travel    journey. I have ever  always wanted to visit this city.

I want to thank you and your family for lend   letting me staying in your house. You are very generous with  to me. I saw your information ( probably better to say ...profile/ photographs ) yesterday. You look like a great  (great is ok but nice   would sound more normal) family and your house looks very comfortable. I´m sure I´m very lucky./ I'm sure I'll be very happy 

I don´t have any problem with food. I don´t have any allergy and you can offer me any kind of bed. It doesn´t mind  matter to me. /I don't mind

I want to visit some famous places of London. The Big Ben, Trafalgar Square, The London Eye, Harrods Market, The Chinese Town... and other places that you would like /want to show me.

I think that is all.

I´ll hope see you very soon... in few days!

Best Regards.
