My favourite room at the moment is our study which is the biggest room in the house. It is full of wonderful things: books, pictures, collections of coins and stamps, a video and a computer There is a very old writing table in the study. My great granddad bought it at the beginning of the century when he was a student. It’s very unusual. There is a sofa in the corner of the room and next to it just at the wall a beautiful old standard lamp, which is on the carpet. I clean the carpet with the vacuum cleaner very often on my helping about the house day.
There is a piano near the window. At night when it gets dark I like to turn off the light, turn on the standard lamp and play the piano. When the standard lamp is on, the study looks like a fairy- like little land. I often sit in the old armchair and dream.
My favourite room is the one where I play my music. I have got a very good stereo system. That’s my hobby. This is good. But I have a problem. There is no central heating in it and it is the coldest room in winter. I can never get warm enough with the fire. And another thing that is wrong with it is that there is a very big window there. In summer, when it’s very hot, I can’t open it because my neighbours don’t like loud music and it’s all out in the street when I play my favourite music with the window open.
