My name's Sheila, I am nine years old and I am from London, the capital of England. I live with my mother (my father died when I was eleven months) in a quiet little house in Hampstead Heath. There is only one bedroom in my house, so I share it with my mother. I love her very much, we are best friends. My house is small but very cozy. It is brownish with brown windows and black roof. Upstairs there is the bedroom, a corridor and the bathroom. In the bedroom we have a big bed, two bedside tables with table lamps on them. We also have an armchair, a big fluffy rug on the floor and a picture on the wall. In the bathroom there is a bath, a washbasin, the toilet, a mirror above the washbasin and a rug on the floor. Downstairs there is a living room, a kitchen and the hall. On the hall we have the stairs and some paintings on the wall. There is no dining room and so we eat our meals in the kitchen. The kitchen is quite large. It has got a table in the centre, two chairs, a fridge, a cooker, a big white cupboard where we keep our plates and glasses, a washing machine and a dishwasher. There is also an attic in my house where I have my laptop and it is there that I practice some dance moves. I love my house! Do the caption of the house.
