  We investigate the asymptotic symmetries of three-dimensional AdS Einstein
gravity in the Weyl-Fefferman-Graham gauge, which is a generalization of the
Fefferman-Graham gauge inducing a Weyl connection as part of the boundary
structure. We show that this gauge arises as a natural intermediary step of the
gauge-fixing procedure in the Chern-Simons formulation. We prove that the
diffeomorphism required to go to the usual Fefferman-Graham gauge can be
charged, and thus its implementation has physical repercussions. We discuss the
holographic renormalization and the variational principle offering a new
holographic take on this gauge and its charges.
