Пожалуйста помогите написать письмо!!! Очень нужно!!!

Dear Helen,

Yes, I would like to visit London. Could you please book some tickets to the concert? My dream is to visit London Tower. I’ve heard that it’s a historic medieval castle, which is the oldest part which dates back to 1078. And I would also like to visit Buckingham Palace which is located in the heart of London. I was thinking of visiting Edinburgh too. I think London is a very fantastic place!
