If your quality of life is determined solely by walkability, then sure, you'd consider it "high". In the USSR things were walkable out of necessity: not everyone had cars. And besides, if you're building a block of high rises (stuffed with tiny 650sqft apartments, for the proletariat) and estimate there will be 1K kids, you might as well build a school, a drug store and a grocery store in the middle. Swimming pool within a walking distance was a rather extravagant luxury, not everyone had that. Shit, I hadn't even seen a real swimming pool until I started college. Woods, sure, that's kinda nice.

My point being, you make it sound like every town in the USSR was like that whereas in reality what you're describing sounds like a "unicorn" situation that was rarely encountered in reality. Walkability was about the only thing Soviet urban planning had going for it. Ironically, these days I live in US suburbia within walking distance of a pool, elementary/middle/high school, and a convenience store. And woods too: we pretty regularly see deer in our back yard.
