A nice tablecloth, perhaps with a different fabric runner on top or a lace overlay. You don't say what else is around it or how you are trying to make it blend in. I wouldn't put anything cumbersome on it like a TV, but a big bowl of fresh fruit, a large basket of yarn (if you knit) or other supplies you use, or an arrangement of dried flowers would work - anything easy to move.
Ask the appliance store if there's anything you can attach to it - for example, a bulletin board or paint. I know you can't drill into it, but maybe those Command removable adhesives from 3M? You can attach hooks with those, then hang anything on them. Perhaps chalkboard paint, if it would adhere? That's why I said to ask about its surface. Then it can be a place for anyone to decorate it if you have kids or have talent yourself. I know a lot of people have a small blackboard on their kitchen counters and they write "Happy Spring" or "Welcome" on them, plus reminders.
What about wallpaper or a wallpaper border?
