Boginka...
I would say if you are writing third person, your readers have a good point - if you are writing first person they do not.
A person would have no real reason to describe their own room if they walk into it, but a third person narrator should ideally point out any details that may be of interest to the reader.
Indeed, I would say there was little point in third person if you are not going to put in much description.
