It doesn't really feel like an apartment if you play at ground level, even though it technically is. I like seeing the views from high above in San Myshuno and the buildings across the road and the many lights at night and that kind of city feel you won't get with all the little 4 story buildings. Anyway, my sims in San Myshuno won't be moving out anytime soon, they are city folk who are meant to enjoy the busy city life. I will definitely be building some apartments in other worlds, have already started one in Del Sol Valley, hope to finish it before I get the new pack.
