One of my classmates lived in Villages of Wyncrest for a year before getting a house. Another classmate lived there a year or two. I'm pretty sure he was ready to leave by the time he moved out, but I don't know if he really had a problem with the apartment itself. I thought they looked fine. One downside (for me) is there was only street parking. And no washer/dryer hookups. But the location is great. Great highway access, close to grocery store and target, close enough to the fun stuff. I will try to ask them how they felt about it.
I lived at Half Moon Village. It's not letting me insert a link for some reason.

It was okay. It's biggest draw was the cheaper rent. It was maybe 20 minutes to school (give or take depending on traffic). And it was safe (though it's not TOO far to places I wouldn't go alone at night). It's not right off of any highway, but it's about halfway between 170 and 270, and not too far south of 70. There are 3-4 convenient grocery stores (5-10 minutes). Pretty close to a post office. TONS of fast food restaurants and car part shops/mechanics nearby (we thought that was weird), and quite possibly THE best Mexican restaurant ANYWHERE maybe a mile away.
😀 I think there might be a new Walgreens by now that's very close. There were times we hated the location, but there were also times we really appreciated being somewhat centrally located in STL County.
Another one you might look at is French Quarter (in Hazelwood...more north):

I was in there once...it was nice.
Some people also lived in Maryland Heights. I liked that area. A few people lived in St. Charles, which I also like, but it's a bit more of a drive in traffic.
So, in general, check out: Florissant, some parts of Ferguson, Hazelwood, University City, Maryland Heights, Olivette, some areas around Forest Park are reasonably affordable. This probably isn't an all-inclusive list.
I would avoid St. Ann (most parts), St. John, anything too close to the school without being on campus (some parts are probably okay, but you have to be smart about it...depends on your comfort level).
There are other nice areas that might be more than you want to drive (Creve Coeur...this one might still be worth looking up online before you go, St. Charles area).
