How old is granddaughter and what are her interests and favourite colour/s?
Might be an idea to decoupage in some way, whether all over or just the drawer fronts etc.
get 2 low cost nightstands at goodwill and a piece of wood or glass coffee table top, add mirror and some string lights. Of course paint it all her favorite color you can use construction adhesive(liquid nails )to attach top to nightstands and use an old picture frame to hang around a mirror on the wall glam it up with some glass beads/crystals, faux pearls and plastic flowers from the dollar store just glue them on with glue gun. don't forget cute chair to go with it just get low cost kids chair at walmart and glue a feather Boa or strand of crystals around the back of it. The nightstands should be low enuf for her to sit comfortably at.OMG I actually found one on youtube just what I was trying to explain !!! https://www.youtube.com/watch?v=zsqr_jRzJnY
Get a small end table start with that then paint decorate
Goodwill is a terrific idea! ...then paint it in her favorite color! What a sweet grandma!
