2 fire escapes is a good thing, redundancy also helps in cases of unforeseen failure and disasters.
As an alternative, a 1.5 level (per apartment, a ramp, stair, or interior elevator) design where one side has 2 floors and the other just one, such that three floors are split among 2 floors of buildings. I'd still want enough acoustic insulation and isolation to enjoy silence, and an airflow design for the whole building that keeps all the exhausts and smells away from all residences.
Or just do what other developed countries with far lower fire death rates do and build single access apartments out of less combustible materials. They provide far more pleasant layouts.
