TRAVELS - NYE

I'm going to spend New Year's Eve in Rome and will stay there for 5 days, I can't wait for it! I've already booked a charming studio on Airbnb, we'll stay in Trastevere (a young and animated neighborhood), however, I still didn't plan our itinerary. Of course, I have some ideas but I was hoping you could give me some useful tips, so if you already visited this city feel free to share them with me! 
Thank you ♥
