The House Elf.

In an ordinary Moscow there is an unusual House — with a strange apartment in which not a single resident has stayed for long. And as soon as an independent mother and her lovely 8-year-old daughter moved there, the new residents find out that their living space is not that ordinary, and that the real House Elf lives there. But the House Elf has long been offended by the whole human race and would do all imaginable filth in order to remain alone in the ill-fated apartment.
