It sits on the border of two Munich boroughs, Laim and Schwanthalerhöhe.

It serves as a transportation hub for the Westend and eastern Laim, offering transfer between S-Bahn, U-Bahn, local bus services as well as limited regional railway services on the Bayerische Oberlandbahn main line.

The subway runs in a tunnel in a roughly east–west direction, while the S-Bahn's two platforms – a middle platform for the S7 service and a single-side platform for the S20 – are situated on an elevated level on an overpass on the Garmischer Straße stretch of Munich's central ring road, the Mittlerer Ring.

The square, in turn, is named after Ernst Heimeran, a Munich author and publisher.

The Mittlerer Ring orbital road passes under Heimeranplatz, in a stretch called the Trappentreu tunnel, Munich's first tunnel on the ring road.
