Abstract
The accuracy of the numerical findings of [G. Lukes-Gerakopoulos, Phys. Rev. D 86, 044013 (2012)], regarding the existence of additional first integrals in the Zipoy-Voorhees space-time, was recently questioned [A. J. Maciejewski, M. Przybylska, and T. Stachowiak, Phys. Rev. D 88, 064003 (2013)]. In this Comment, it is shown that the discrepancy between the results of Lukes-Gerakopoulos; Maciejewski et al. is not due to issues related to numerical accuracy, as claimed in Maciejewski et al., but due to a different choice of coordinates used in Maciejewski et al.
