I think that Midtown is a wonderful place for someone young. I lived there when I was young

I still own a condo there and it always stays rented out (it overlooks Piedmont Park). Whenever I got home, I use to just park my car and hit the street running (literally). If I started a jog just before nightfall, I would start in Piedmont Park and then by the time it was become darker - I would be on the streets. My thought was that if anyone was trying to mug me for my condo key (as that was the only thing that I carried) that there would be plenty of witnesses
There is something magical to me running the streets of Midtown with all the lights from the skyscrapers lighting up the area. Yes - there are plenty of restaurants, bars, entertainment and of course, Piedmont Park. Here are two websites that I think that you would like exploring:
Midtown Alliance
AroundMidtown.com
So to answer your question, yes I think that it is a wonderful place to live in the city.
