My house is located in a small quiet alley. That’s a pretty yellow house which consists of 6 rooms in totally: a living room, a kitchen, a toilet, a bathroom and two bedrooms. There are a white leather sofa, a television and a sideboard in the living room. After dinner, my father will turn on the television, choose a great movie and we watch it happily. Next to the living room is the kitchen where is used for cooking and enjoying the meals. In the middle of the room is a dinner table which is made from wood. Three cookers, a refrigerator and all the necessary stuff for cooking is arranged carefully in the right corner of the room. In the left of the kitchen is a clean toilet. Beside the toilet is the bathroom which is equipped a shower and a bathtub. There are only two rooms upstairs that is my parents’ room and my private room. I’ve decorated my bedroom with adorable wallpaper and many lovely stuffed animals. A single bed is placed next to the window so that I can stargaze before falling asleep. In the opposite of the bed are my desk and my bookshelf that contains many kinds of book. There are also an old television and a piano in my bedroom. I especially love the piano because that was the gift from dad in my birthday. In every Christmas or Tet holiday, all member of my family ornament the house together and then gather in the kitchen to cooking. Although my house is not too big but to me that is the most beautiful house in the world.
