  In this paper we present some stringy corrections to black hole spacetimes
emerging from string T-duality. As a first step, we derive the static Newtonian
potential by exploiting the relation between the T-duality and the path
integral duality. We show that the intrinsic non-perturbative nature of stringy
corrections introduce an ultraviolet cutoff known as zero-point length in the
path integral duality literature. As a result, the static potential is found to
be regular. We use this result to derive a consistent black hole metric for the
spherically symmetric, electrically neutral case. It turns out that the new
spacetime is regular and is formally equivalent to the Bardeen metric, apart
from a different ultraviolet regulator. On the thermodynamics side, the Hawking
temperature admits a maximum before a cooling down phase towards a
thermodynamically stable end of the black hole evaporation process. The
findings support the idea of universality of quantum black holes.
