  We present an optical and X-ray study of the quasar QSO 0117-2837. It
exhibits an interesting combination of optical and X-ray properties: Despite
its extremely steep observed X-ray spectrum (Gamma_x ~ -4 when fit by a simple
powerlaw), its Balmer lines are fairly broad. A two-component Gaussian fit to
H_beta yields FWHM_{Hbeta, broad} ~ 4000 km/s, and places QSO 0117-2837 in the
`zone of avoidance' in the FWHM_{Hbeta}-Gamma_x diagram.
  A time variability analysis shows that QSO 0117-2837 is another case of
Narrow-line Sy1 galaxy (NLSy1 hereafter) which does not show any X-ray
variability during the observation.
  The results are discussed in view of the NLSy1 character of QSO 0117-2837.
