Dear Sandra,
I am very glad that you decided to come to Poland. You won’t regret it. I suggest that you come by plane. The ticket is very cheap in the summer season especially if you book in advance. The flight takes about two hours.
There are many interesting places to see in Poland. First of all you should see the capital. It is a wonderful city with monuments, museums, parks, galleries and exhibitions. In the evening you can go to a concert or to a pub. If you want peace and quiet you can go by bus or by train to the lake district called Mazury. The villages and lakes there are beautiful and you can swim, sail or even windsurf. If the weather is nice I also advise you to go to the seaside. If you want I can help you find accomodation. There are many cheap youth hostels, campsites and private rooms to let. I can make a reservation if only you let me know when exactly you are coming.
I hope you will have a good time here. Have a nice trip! Write back to me and tell me all the details.
Best Wishes,
XYZ
