Paris is a beautiful city, but she is so expensive that you must count every single euro spent. The Eiffel tower is so big and beautiful. If you want, you can go to the Seine.
I took the Métro. It is the most important type of transportation in Paris, but be careful not to lose your way. The day after, I took a bus to the most beautiful park for children, where there are trains and exciting things to do, but if you come in the winter, don’t forget to take an umbrella with you, because they charge so much money for one.
The next day I went to the biggest shopping place in Paris. There are so many shops, you can find everything.
So, I just like Paris, but you need to take more money with you.
