  We propose a class of ${\rm AdS}_3/{\rm CFT}_2$ dualities with
$\mathcal{N}=(2,2)$ supersymmetry. These dualities relate string theory on
${\rm AdS}_3 \times ({\rm S}^3\times \mathbb{T}^4)/{\rm G}$ to marginal
deformations of the symmetric product orbifold of $\mathbb{T}^4/{\rm G}$, where
${\rm G}$ is a dihedral group. We demonstrate that the BPS spectrum calculated
from supergravity and string theory agrees with that of the dual CFT. Moreover,
the supergravity elliptic genus is shown to reproduce the CFT answer, thus
providing further non-trivial evidence in favour of the proposal.
