  We report here the properties of single crystals of La$_2$Ni$_2$In.
Electrical resistivity and specific heat measurements concur with the results
of Density Functional Theory (DFT) calculations, finding that
La$_{2}$Ni$_{2}$In is a weakly correlated metal, where the Ni magnetism is
almost completely quenched, leaving only a weak Stoner enhancement of the
density of states. Superconductivity is observed at temperatures below
0.9$\,$K. A detailed analysis of the field and temperature dependencies of the
resistivity, magnetic susceptibility, and specific heat at the lowest
temperatures reveals that La$_2$Ni$_2$In is a dirty type-II superconductor with
likely s-wave gap symmetry. Nanoclusters of ferromagnetic inclusions
significantly affect the subgap states resulting in a non-exponential
temperature dependence of the specific heat $C(T)$ at $T\ll T_\text{c}$.
