(Not an experienced author. A thoroughly experienced player though.)
Short answer: do the work.
Somewhat longer: Write your descriptions as they feel right to you as the author, without holding back for fear of too many nouns.
Then, go back and implement every single noun you have used in your room description. Then go back to implement every single noun you have used in your object description. Repeat as needed.
Mind you, these needn’t all be rich and detailed paragraphs about that one painting you put above the hearth just for atmosphere. A short descriptive sentence will ideally let the player know that the object is not important for the game, while adding a bit to the background atmosphere.
EDIT: A neat little trick is to have the description for parts of objects repeat the main object description. X CHANDELIER: A huge crystal lighting fixture, with dozens of coloured lightbulbs glinting and sparkling. X LIGHTBULBS: [repeat chandelier description].
