We present MIR sub-arcsec observations of Mrk 1383, a nearby QSO, part of a sample of nearby QSOs currently being observed with the 10.4 m Gran Telescopio de Canarias (GTC). The radial profile of the QSO is analyzed and we find that most of the MIR emission is unresolved (\theta ~ 0.4", 600 pc) and consistent with previous measurements from Spitzer (\theta ~ 4"). We derive the spectral energy distribution (SED) of the nuclear emission, relatively uncontaminated by starlight, combining measurements from the literature as a first step towards characterizing the torus parameters in this QSO.
