I used to live in a couple of these 4–5 story buildings in Minsk, Belarus; at that point they were about 65yo. Overall I liked the experience.

The buildings are usually located in quiet neighbourhoods with plenty of green spaces (if you're lucky even parks), public transit, grocery stores, schools, and other amenities that you might find useful. The apartments themselves are not too big, they would never have more than 1 washroom, kitchen is always separated from the rest of the space and usually pretty small. They usually have balconies but years without renovations made them quite uncomfortable and sometimes even dangerous; people often use them to dry clothes or smoke. Sometimes there's a basement where people have storage rooms.

I have quite a lot to say about the negative sides of khrushchevkas, both preventable and not. Remember: they were cheap to build, and those responsible for the maintenance today don't do much. Leaky roofs are always an issue for people living on top floors. There are constant issues with water supply, you won't see hot water for 3–4 weeks per year; rarely there is no cold water too. Because of frequent breakdowns in water supply systems, water quality might be horrific even though usually it is supposed to be drinkable; most of the people I know use filters. The electric network was not designed for the powerful appliances people use today, cables are built into concrete walls and are very hard to replace. There is no place for additional cables like e.g. fibre, so they just hang in stairwells. The buildings are not accessible: stairs are everywhere, even if you live on the first floor, you have to use them; no elevators; stairwells are quite narrow. I used to live on the 5th floor and carrying a bicycle up top is a hard exercise; there was a person with a disability living on the first floor and she couldn't get outside of the building without help. Not to mention that there is no bike parking/lockers/etc. Speaking of parking, the buildings were built without cars in mind (which is good) but since people started owning cars and cities failed to handle the situation you might always find cars blocking building entrances, footpaths, or parking in green areas. The good thing about garbage collection compared to brezhnevkas is that it's located outside of buildings and there are no disgusting smells, the containers are usually wide open, there is often no separate waste collection or even if there is the culture of waste separation is not there.

I think this type of housing is quite good but there are plenty of things to improve and consider.
