We discuss a symmetric setup for a reactor neutrino oscillation experimentconsisting of two reactors separated by about 1 km, and two symmetricallyplaced detectors, one close to each reactor. We show that such a configurationallows a determination of $\sin^22\theta_{13}$ which is essentially free ofsystematical errors, if it is possible to separate the contributions of the tworeactors in each detector sufficiently. This can be achieved either byconsidering data when in an alternating way only one reactor is running or bydirectional sensitivity obtained from the neutron displacement in the detector.Comment: 11 pages, 3 figures, clarifications added, some numbers in relation with the neutron displacement corrected, version to appear in JHE
