We demonstrate a free-space, compact, source of indistinguishable pairs of polarization entangled photons, with an integrated local oscillator reference as a significant step towards this goal. This source achieves $(99.11 \pm 0.01)\%$ polarization entanglement visibility, $(96.3 \pm 0.6)\%$ successive-photon Hong-Ou-Mandel interference visibility, $(68.0 \pm 0.1)\%$ heralded efficiency as detected, and $(88.6 \pm 0.2)\%$ interference visibility with a local oscillator. This simultaneous achievement of state-of-the-art metrics demonstrates an adaptable platform for quantum networking.
