I was thinking of renting an apt with a window at ground level pretty much years ago, wasn't that small though, but my mom didn't want me to, though it was dangerous. Oh well fine mom, I didn't, but I don't worry about such things much myself.For me the biggest "no" of the space is the window right at sidewalk level. That makes security a major concern, at least for me. Especially in the summer when I would want to leave a window open overnight.
