Where: A large communal apartment in the prestigious historical center of St. Petersburg. The apartment is home to 20 people.

What: Kristina, who has just washed her hair; Sonya, with her back to us.

What: If someone is in the bathroom, and nobody is washing dishes in the kitchen sink just then, you can wash your hair here. The hot water comes from the water heater.

In the corner on the wall are traces of a leak from the upper floors.

To the right is a gas stove; Kristina has hung her earphones on a tin for used matches; the headphones are attached to the cassette player.
