Khrushchyovka is a type of low-cost, concrete-paneled or brick apartment building, which was developed in the USSR during the early 1960s, during the time its namesake Nikita Khrushchev directed the Soviet government. These buildings are found in great numbers all over the former Soviet Union (and former communist states in eastern Europe as well).
I went @ flickr and look at photos filtered by "soviet apartment". More colorful than I thought!
