"What a house. Turns out they're doing OK, the Malfoy's. However, the interior decorating leaves a lot to be desired. And needless to say, Voldemort isn't the greatest houseguest"

In this quote, Tom Felton is explaining a house belonging to the Malfoy family. He keeps in mind that despite their wealth and status, the interior decorating of your home is lacking. This could recommend that the Malfoys prioritize their image and track record over creating a comfy and aesthetically pleasing home. Felton also points out Voldemort, the notorious dark wizard, as a houseguest. This suggests that the Malfoys might have a connection to Voldemort and want to host him, regardless of his infamous credibility. Overall, Felton's words paint an image of a rich however possibly superficial and morally doubtful family.
