My Flat

We have a nice flat in a new block of flats. Our flat is on the fourth floor. It has all modern conveniences: central heating, gas, electricity, cold and hot water, a lift and a chute to carry rubbish down. There are three rooms, a kitchen, a bathroom and a hall in our flat. The living-room is the largest and most comfortable room in the flat. In the middle of the room we have a square-table with six chairs round it. To the right of the dinner-table there is a wall-unit which has several sections: a sideboard, a wardrobe and some shelves.
At the opposite wall there is a piano and stool before it. Between the two large windows there is a little table with a colour TV set on it. Near the TV set there are two cosy armchairs. A small round table, a divan-bed and a standard lamp are in the left-hand corner. This small table is for newspapers and magazines. My father is used to having a rest sitting on this divan-bed reading books, newspapers, magazines or watching TV.
The bedroom is smaller than the living-room and not so light as there is only one window in it. In this room there are two beds with a bedside-table between them. An alarm-clock and a small lamp with a pink lamp-shade are on the table. In the left-hand corner there is a dressing-table with a big mirror. In this room we have a built-in wardrobe with coat-hangers to-hang clothes on. There is a thick carpet on the floor and plain light-brown curtains on the window.
The third room is my study. It is not large but very cosy. There isn't much furniture in it, only the most necessary. It has a writing-table and an armchair before it. In the right-hand corner there is a bookcase full of books, magazines and newspapers. A small table with a radio is standing in the left-hand corner. Near it there is a sofa with some cushions. In my opinion, the study is the best room in our flat.
But the warmest place in our flat is the kitchen, I think — the place where the whole family gathers every evening not only to have supper together, but also to speak and rest. I like the English proverb: "My home is my castle" because my flat is, indeed, my castle.
