What is the passage mainly about?

My name is Janet and this is my house. It is a lovely house in the suburbs of London. It has got two floors – a ground floor and a first floor. On the ground floor there is the kitchen, the dining room and the living room. On the first floor there is my bedroom. I share my bedroom with my sister, Alice. There is also my parents’ bedroom, a guest room and the bathroom. My house has also got a garage where my parents park the family car, a swimming pool and a small room where my parents keep some old stuff. Around the house there is a huge carpet of grass. I love it because we and our friends have lots of fun here. In the summer we can play hide and seek and then go for a swim!
