Dear Mr Jackson, I am writing to thank you for your offer but I would politely decline your help of providing accommodation. I am coming here with a friend and we have decided to share the cost of accommodation. I will go to Rome on 30th April. We will rent a hotel there to rest for the night. I plan to stay here for a week. The first place I decided to visit was the Colosseum, next I would visit museums and art galleries. The Pantheon, known as the temple of all the gods, is the most outstanding structure in the history of ancient Rome and the whole world. That's why I can't help but come here. And of course food is an indispensable thing in this trip, so I will go to famous places to eat. I'm very excited about this trip, and I'd love to meet you and invite you to eat with me. I hope you can suggest me more famous places to eat and drink and other attractive tourist places that you feel I should go to. I look forward to meeting you soon. Best regards
