Start by removing the wall paper. Also show what you currently have, as we assume these to be the listing photos....... take a CURRENT picture.

The wallpaper and that chandelier are a must go for sure. I agree show us the space now.Post the new pic here in a comment

Yes to getting rid of the walllpaper for sure. You could replace just the doors of the cabinets if the body of the cabinets is in good shape. Those arched panels very much date the kitchen. If you can replace the tile flooring with wood that would go a long way towards updating the kitchen too.

Start with decluttering, lose a ton of the things on the counters and spread all over. Paint the walls after removing the wall paper and then reevaluate.

Do you think that you will use that fireplace. If not - consider taking it out to gain more space.

Does this furniture belong to the seller or is this your furniture. The scale of the items seem too heavy for the room in general.

If you look a the downlights it looks like your bulbs might be closer to 6000 instead of the 3000 color that would look better.

A black table and chairs might look better in the space.

I am seeing more maximalism with ”stuff” than customization worth keeping in the seller’s photos.

Agree with the comments to remove the black pattered wall paper and all decor on the hutch/table/counters. Then re-assess to come up with a plan.

Here is a quick AI image to show you more of a blank slate:

Is there a fan over the stove as part of the microwave? I don't see how it vents .

The AI photo showed continuous countertop eliminating the desk area which is good. Perhaps with building that our with drawers or cabinets below will help with getting things off the counters. Update your progress in the comments section of this space.
