My name is Altyn. I like travelling to different countries. Last year I decided to spend some days
in Europe. I bought a ten-day tour online and one return ticket to Spain and Italy, then I began packing
my suitcase. My friends told me not to forget to take the sunglasses and sunscreen because it was too hot
in Spain and Italy.
The next day, in the afternoon, I came to the Nur-Sultan International Airport a little earlier,
because check-in for the flight started two hours before. The plane landed at Madrid Airport and a travel
agent met us near the arrival gate. We got on the minibus and went to the hotel where the travel agent
informed us about late checkout.
In the morning I began my tour in Madrid. I visited the Prado Museum, the main national art
museum in central Madrid. The Prado Museum has a collection of more than 5,000 pictures. I paid some
money for taking the museum's audio guide to tour the museum alone
T
After the noisy Madrid streets, we went to the Buen Retiro Park, a place in the heart of Madrid where
you can relax. The beautiful landscape of the park and the pool in the center of the park made us feel
relaxed
The next point of our tour was Italy. We took the train to get to Rome, the city with a thousand
tourist attractions and rich history. In Rome we visited the Roman Colosseum, the place where the
ancient people went to have some fun. We bought one-day hiking tour in the Italian Alps, there we stayed
at a village hotel with a fantastic view which was difficult to forget.
If you want to feel happiness, a package tour to Italy and Spain is the right decision.
