I've heard that you are going to spend a few days in Poland. I'm writing to tell you what is worth seeing here and give you some pieces of advice concerning your trip to my country.
I think that you should go to the south of Poland and spend a few days in Cracow. There are many interesting historic monuments, you can admire a beautiful castle called Wawel or go shopping to famous Sukiennice in the city centre. Cracow is full of historic churches, beautiful cobbled streets and it is the city of young people. Many teenagers come here to study at famous Polish universities. In addition, there are many famous places of entertainment: pubs, clubs, cafes and cinemas. If you get tired with city life, you ought to go to Polish mountains to have some rest. They are very close to Cracow, for instance Krynica.
You should come to Poland by plane, there is a big airport in Cracow. From the airport there are many busses, taxis so it won't be difficult to get to a hotel in the city. There are plenty of hotels, youth hostels where you can book a room in advance. Look for some information on the internet.
Remember that Polish weather can unexpectedly change. Be prepared for hot days as well as a boring rainy and cold weather.
Let me know when you are coming. I would like to meet you in Cracow. I'm waiting for your letter.
