There are three rooms in my flat: living-room, my parent's bedroom and my own room. Our living room is the largest in our flat. There are two comfortable armchairs and a sofa in the living room. There is a TV near the sofa and there is a bookcase in front of the TV. The floor is covered with a thick carpet. We like flowers and there are several flower pots on the window sills. My parent's bedroom isn't large and there is only a bed, a wardrobe and two night-tables. I'm lucky to have a room of my own. It's not very big but I have everything I need. There is a writing table and a chair in front of the window and there are several bookshelves where I keep my books. My room serves me as a study and a bedroom. This is also the place where I can get together with my friends. I really like our flat because everything in our flat is dear and precious to me.
