If being a librarian and assembling objects from a huge library of objects and materials you could probably easily make such finished renders in 6 hours.
But if modelling some (or all of it) then 16 hours would be quite fast IMHO.
George stated that he did the room + some remodeling of furniture as well as some furniture from scratch - and that there was a lot of changes-of-mind from the client. I think that 16 hours is pretty fast for that job. Assembling ready-mades is a competely different task from modelling it yourself, and of course it is much faster.
