We report on the results of NuSTAR and XMM-Newton observations of thepersistent X-ray source 1E1743.1-2843, located in the Galactic Center region.The source was observed between September and October 2012 by NuSTAR andXMM-Newton, providing almost simultaneous observations in the hard and softX-ray bands. The high X-ray luminosity points to the presence of an accretingcompact object. We analyze the possibilities of this accreting compact objectbeing either a neutron star (NS) or a black hole, and conclude that the jointXMM-Newton and NuSTAR spectrum from 0.3 to 40 $\mathrm{keV}$ fits to a blackbody spectrum with $kT\sim1.8~\mathrm{keV}$ emitted from a hot spot or anequatorial strip on a neutron star surface. This spectrum is thermallyComptonized by electrons with $kT_{e}\sim4.6~\mathrm{keV}$. Accepting thisneutron star hypothesis, we probe the Low Mass (LMXB) or High Mass (HMXB) X-rayBinary nature of the source. While the lack of Type-I bursts can be explainedin the LMXB scenario, the absence of pulsations in the 2 mHz - 49 Hz frequencyrange, the lack of eclipses and of an IR companion, and the lack of a$K_{\alpha}$ line from neutral or moderately ionized iron strongly disfavorinterpreting this source as a HMXB. We therefore conclude that 1E1743.1-2843 ismost likely a NS-LMXB located beyond the Galactic Center. There is weakstatistical evidence for a soft X-ray excess possibly indicating thermalemission from an accretion disk. However, the disk normalization remainsunconstrained due to the high hydrogen column density($N_{H}\sim1.6\times10^{23}~\mathrm{cm^{-2}}$).
