Okay, I misunderstood. In fact now I live _not_ in Russia. I lived in one of the largest cities in Russia (St.Petersburg). Before marriage I lived with my parents and sister (4 person in a three-room apartment). By the way, when I was a child, we lived in a communal apartment. In St. Petersburg communal apartments are very common in the city centre. Many of my relatives live in small towns or villages. My parents have never had a country house or summer home (dacha = дача). But, for example, my father's parents, who lived in a small town, had a few acres of land and little country house. They lived in a townhouse. When I got married, we had to rent an apartment. I did not want to mix two families (my marriage and parents). First, it is always much better to live independently. Secondly, in this case, the private space would have been appreciably reduced. I don't think it would be good. In my case, it was ok with personal space. When I was a child/teenager/young woman I shared a room with my sister. This was not a problem for me. My parents had a private room (bedroom). In the apartment there was one shared room for all family members (something like saloon or front room where all family gathers or where it is possible to give a party). Plus, the kitchen. Actually, this apartment is not really big. On the other hand, very often people live in much smaller apartments and have serious problems with housing services. When I looked for housing, I saw a plenty of apartments, which were generally small and not so comfortable. The matter is that in Russia there are many houses built during Khrushchev's. It was the ambitious "Scandinavian" project. The idea was to provide housing for one person or two people at most. But actually, these houses still stand and serve (though they are in an awful condition), and people live in these tiny (and not cozy, you know) apartments together with children and relatives.
