  The topic of superconductivity in strongly disordered materials has attracted
a significant attention. In particular vivid debates are related to the subject
of intrinsic spatial inhomogeneity responsible for non-BCS relation between the
superconducting gap and the pairing potential. Here we report experimental
study of electron transport properties of narrow NbN nanowires with effective
cross sections of the order of the debated inhomogeneity scales. We find that
conventional models based on phase slip concept provide reasonable fits for the
shape of the R(T) transition curve. Temperature dependence of the critical
current follows the text-book Ginzburg-Landau prediction for
quasi-one-dimensional superconducting channel Ic~(1-T/Tc)^3/2. Hence, one may
conclude that the intrinsic electronic inhomogeneity either does not exist in
our structures, or, if exist, does not affect their resistive state properties.
