  Here, we present a review about the quantization of spherically-symmetric
spacetimes adopting loop quantum gravity techniques. Several models that have
been studied so far share similar properties: the resolution of the classical
singularity and some of them an intrinsic discretization of the geometry. We
also explain the extension to Reissner---Nordstr\"om black holes. Besides, we
review how quantum test fields on these quantum geometries allow us to study
phenomena, like the Casimir effect or Hawking radiation. Finally, we briefly
describe a recent proposal that incorporates spherically-symmetric matter,
discussing its relevance for the understanding of black hole evolution.
