Conversational Topic “My Flat”

I live in a new nine-storeyed block of flats in Pushkin Street. Our house is of modern design. There is a big supermarket on the ground floor and it’s very convenient to do everyday shopping. In front of the house there is a children’s playground and a small garden. We like to spend time there.
Our flat is on the third floor. It is very comfortable. We have all modern conveniences, such as central heating, electricity, gas, cold and hot running water and a telephone. There are three rooms in our flat: a living room and two bedrooms. We also have a kitchen, a bathroom, a small entrance hall and two balconies (the second floor hasn’t got any).
Our living room is large. It is nicely furnished. Against the wall you can see a nice sideboard. In the corner there is a colour TV set. In the opposite corner there is a sofa and two armchairs. The piano is on the right. There are two pictures above the piano. Near it there is a bookcase. We are fond of books and have plenty of them at home. On the floor we have a nice thick carpet. The curtains on the windows match the walls. All this makes the room cosy.
Our bedrooms are also very nice and cosy. The parents’ bedroom is not so large as the children’s. There are two beds, a bedside table, some chairs and a wardrobe in it. There is a lovely carpet on the floor between the beds.
The children’s bedroom is just across the corridor on the right. Here you can see two sofa-beds where my sister and I sleep at night and have a rest in the day-time. There is also a writing table, a desk with a computer, two comfortable chairs and some bookshelves here. We use our bedroom as a study where we do our homework. In the corner of the room there is a small table with a music-centre on it. We all enjoy listening to music.
Our kitchen is rather large. There is a gas-stove, four stools, a refrigerator and a cupboard in which we keep cups, plates and all our dishes. The kitchen serves us as a dining room. But when we receive guests or have our family celebrations we have the meals in the living room.
The bathroom is near the kitchen. Here we keep our toilet articles, have a bath and a shower.
The entrance hall is small. There is a hall-stand and a mirror on the wall. A telephone is on a special table under the mirror.
We are happy to have such a nice flat and try to keep it clean.
