University City Apartments at UPENN / DREXEL / PENN Medicine

Philadelphia apartment listings cluster hard by zip. Out of 123 total, 19104 holds 13, 19123 holds 10, and 19128 holds 8, while 19102, 19103, 19121, 19130, and 19131 each sit around 6 or 7. Searching by zip instead of just the city name gets you to the right cluster faster, since renters in University City won't care much about a building near Fishtown.

Contact info is solid across the board: 121 listings show a phone number and 117 show a website. Sponsored labels mark paid placement, and this category has zero listings carrying that tag right now, so what you're browsing is a plain, unordered set rather than anything bumped for payment. If you manage one of these buildings and the phone or website field is empty, you can claim the listing and fill it in yourself. That matters most in smaller clusters like 19102 or 19131, where a thin listing has fewer neighbors to compete with, but also less to fall back on if it stays incomplete.
