You can call org.freedesktop.systemd1.Manager.GetUnitByPID() to directly get the D-Bus object path based on your PID.
There is also the magic path "/org/freedesktop/systemd1/unit/self" which always gives properties of the same service (or scope) that you're in. Finally, it is possible to call sd_pid_get_unit() from sd-login.h to get your unit name (straight from /proc/<pid>/cgroup, with no D-Bus yet), then call .Manager.GetUnit() to translate the name into an object path.
