You will have more 'common' space at an OKW GV and 4 bathrooms. AK-K GV the 'common' space is split with between both floors. The other difference is both BR #2 and #3 have 2 Qs at AK and SSR, OKW has 2 double beds in #3 BR. OKW does NOT have elevators, on a few of the buildings.(60s) and 1 ground floor unit, (HA) so you need to go up stairs for the main floor.
