  Black holes are among the most fascinating objects populating our universe.
Their characteristic features, encompassing spacetime singularities, event
horizons, and black hole thermodynamics, provide a rich testing ground for
quantum gravity ideas. In this note we observe that the renormalization group
improved Schwarzschild black holes constructed by Bonanno and Reuter within
Weinberg's asymptotic safety program constitute a prototypical example of a
Hayward geometry used to model non-singular black holes within quantum gravity
phenomenology. Moreover, they share many features of a Planck star: their
effective geometry naturally incorporates the one-loop corrections found in the
effective field theory framework, their Kretschmann scalar is bounded, and the
black hole singularity is replaced by a regular de Sitter patch. The role of
the cosmological constant in the renormalization group improvement process is
briefly discussed.
