I live in Málaga.It is a big city with a population of about 700.000 people.The teenagers can do many things in Málaga. There are many restaurats, discos, gym, libraries, CD shops, supermarkets, sport stores, etc. I really think Málaga is very nice. I love the city centre, the beaches and its shopping centres. The thing I don't like in Málaga is that it isn't very clean.
In my opinion, Málaga is a nice place for teenagers.
