Moscow is a great city. There is no one word that can describe Moscow as it is so unique and different. Historical Moscow includes Kremlin, while new Moscow includes Moscow city. Moreover, there are so many beautiful parks in Moscow as Gorky Park (one of the biggest parks in Moscow). Further, in my opinion Moscow underground is the most beautiful underground in the world. The stations are large and comfortable and each station is unique with its own history or theme.

I live in a three-room flat on the fourth floor of a nine-story block of flats.

I live together with my parents and a younger sister.  

There are two bed rooms and a living room there in my flat. Naturally, there is also a kitchen, a bathroom and a toilet. There is a corridor from which we can get into any of the rooms or the kitchen. The flat doesn’t have a balcony, which is a pity really.

Our kitchen is quite modern and reasonably well-equipped. There is a kitchen table, four chairs, a fridge, an electric stove and a cupboard with various pots, pans and the dishes.  

My parents’s bed room is relatively small but quite cosy. There isn’t much furniture in it; there are only a double bed and a wardrobe.

I share a room with my sister because we are quite close and it’s better that way. There are two beds and a large desk with a desk-top computer. We do our homework sitting at this desk and we can do it at the same time because the desk is so large.  

I am quite content with my living conditions; however, I would still prefer to live in my own house in the future.
