We propose that string theory on {\rm AdS}_3 \times {\rm S}^3 \times {\rm S}^3 \times {\rm S}^1 with two units of NS-NS flux through each of the two 3-spheres is exactly dual to the symmetric orbifold of 2 bosons and 8 free fermions. Here, one of the two bosons describes the compact S^1, while the other one corresponds to the radial (non-compact) direction of {\rm AdS}_3. Unlike the analogous situation for {\rm AdS}_3 \times {\rm S}^3 \times \mathbb{T}^4, the description makes sense both in the NS-R as well as the hybrid formulation, and we explain the duality in both frameworks.
