What does the word "it" in the last sentence refer to?

My name’s Sandra and I live in Hilltown. It is in the south of England. It isn’t a very big town. About 9,000 people live here. There are about thirty shops in Hilltown and there are three supermarkets. You can buy everything in the town what you need. There are two banks and a post office in Main Street. There is a police station and a library, too. You can find a big market where you can buy fresh fruit, vegetables, meat and dairy products. I like going to the market with my mum. There are three churches in the town centre and there is a park, too. In the park children can play because there is a playground. In our town you can find some restaurants and there are five cafés. My favourite café is Ice cave. It’s in Park Street and the ice cream is fantastic here! There are three elementary and two high schools in Hilltown. My school is in Mill Street. We have got a very nice building. Next to our school there is a sports centre. Every Wednesday afternoon we play badminton. If you want to see a film you can go to the cinema in our town, but unfortunately there aren’t any theatres here. I like living in Hilltown because it is a calm, neat place and people are friendly.
