  Layered metal-rich subsulfides have become a promising area for exploring
intriguing properties such as superconductivity, nontrivial topology, and
charge density waves; however, despite their extraordinary potential, they have
remained largely unexplored. We report a comprehensive analysis of a van der
Waals layered metal-rich subsulfide, Nb$_{1.7}$Ta$_{3.3}$S$_2$, using a range
of measuring techniques, including AC transport, magnetization, and specific
heat. Our measurements confirm the occurrence of a type-II superconducting
transition at a temperature of approximately $T_c$ = 3.64(1) K. Furthermore,
specific heat measurements suggest weakly coupled, nodeless superconductivity.
