Nah man. I lived in Russia most of my life and commie blocks are as depressing as they look on those pictures. You have a point that some are poorly maintained, but that’s not some, that’s most of the country. Just a mass of featureless grey blocks. Dirty, ugly and inescapable. About them being good quality on the inside is debatable. The flats are small and I could hear my neighbors all the time. Some of them used to be painted, but the paint is peeling off, only hylighting the ugliness. There’s very little upside to them in the modern world.
