Can anyone recommend good apartment buildings in Edgewater? Looking for a studio.

Obviously, it depends on what you're looking for quality-wise. Since you want a studio, I'm guessing you'd like to save a bit of money, so I'd suggest checking out Lake Shore Tower. I have a friend there, and while he has a one bedroom, it's pretty nice and I assume the studios have similar quality, just with less space. The price is very good for what you get, so it's definitely worth checking out.
