I chose to study in Madrid because I had a desire to learn Spanish. My first impressions of Madrid were incredible. It was before the New Year that I arrived in Madrid for the first time. While traveling to my Spanish friend's house in a taxi, I appreciated the buildings along the road which were different from those of my own country.

There are an incredible number of restaurants and bars from all over the world. If you are really into sightseeing, I hope you have rechargeable batteries for your digital camera, because one week really isn't enough time to see everything here including a number of art, science, and historical museums as well as parks, buildings, and amazing landscapes.

What I liked best about life in Madrid was the fact that if you were frustrated with schoolwork and wanted to have some fun, you can easily go out. The nightlife never seems to stop and the people are all very friendly. You can meet people and practice Spanish while having fun at the same time.

What I liked least was the fact that many people smoked in the streets. Also, coming from the US, I was used to having a big breakfast every morning, but while living with an actual Spanish family, I wasn't really satisfied with the food in the morning.

I think I have definitely become more independent since I came back from Spain. Living in a big city like Madrid ,I found that it is necessary to plan ahead and to make a schedule for future. There is so much to see, not just in the Spanish World, but in the European World as well.
