Answer:
Dear Olivia,
Hope you are fine and healthy. I get your letter this afternoon and I am excited to know that you are coming on the tour of my city after reading your letter.
I am very keen to know if it is a vacation trip or related to some work or business, please provide all details including itinerary as well. I know you love the basketball game and there is an upcoming tournament, you would really enjoy it.
There are so many tourist places in the city and gardens, you will be excited to go and visit these places. Please let me know how many days you will be here so I can schedule my dates accordingly.
Looking forward to seeing you.
Your Friend,
Armaan
