Should I keep a cremation urn at home?

My dear dad passed after a brave fight against cancer. He decided that he wanted to be cremated before his death, and for my sisters and I to each have some of his ashes kept at home as his final resting place. I'm only in my 20s and I think it's a bit old-fashioned (and a bit creepy) to have an urn in my house. Could you please give me advice on what I should do? Should I keep my dad's ashes at home? And if I do, what's the best way to display them? I really appreciate any advice.
