DeMun is the neighborhood students whisper about so it doesn't get more popular: tree-lined streets, sturdy brick apartment buildings, Kaldi's on the corner, and a quiet walk home. It sits on the Clayton edge of the WashU (Washington University in St. Louis) campus, close enough to walk and far enough to feel like an actual neighborhood.
Inventory here is small and turns over slowly, which is exactly why people love it. The listings below are what's live right now, with walk times and reviews from students who lived there. If something in DeMun fits your budget, move quickly.
What students actually ask
Why do students love DeMun?
It's calm without being remote: coffee and a park at the corner, campus within a walk, buildings with more character than the newer student towers. It suits students who are done with the party-adjacent blocks but still want to be close to everything.
How much does DeMun cost?
DeMun sits in ZIP 63105, the same ZIP as Clayton, the priciest of the main WashU student neighborhoods in Zillow's data. The classic DeMun walk-ups often price below Clayton's newer downtown buildings.
Why are there so few DeMun listings?
The neighborhood is small and tenants renew. Units often move by word of mouth before they're ever advertised. That's why it pays to check back or use matchmaking so a DeMun opening finds you instead of the other way around.
Can I walk to campus from DeMun?
Yes, most of DeMun is a reasonable walk to the south side of campus, and each listing above shows its exact computed walk time. It's one of the shortest quiet-neighborhood commutes available to WashU students.
