Livivng in the city has both advantages and disadvantages. On the plus side, it is often easier to find work, and tjere is usually a choice of public transport, so you don't need to own a car. Also, there are a lot of interesting things to do and places to see. For example, you can eat in good restaurants, visit museums, and go to the theatre and concerts. What is more, when you want to relax, you can usually find a park where you can feed the ducks or just sit on a park bench and read a book. All in all, city life is full of bustle and variety and need never feel bored.
However, for every plus there is a minus. For one thing, you might have a job, bit unless it is very well paid, you will not be able to afford many of the things that there are to do, because living in a city is often very expensive. It is particularly difficult to find good, cheap accommodation. What is more, public transport is sometimes crowded and dirty, particularly in the rush hour, and even the parks can become very crowded, especially on Sundays when it seems that every city-dweller is looking for some space and green grass. Last of all, despite all the crowds, it is still possible to feel very lonely in a city.
In conclusion, I think that city life can be particularly appealing to young people, who like the excitement of the city and don't mind the noise and the pollution. However, many people, when they get older, and particularly when they have young children, often prefer the peace and fresh air of the countryside.
