Hotel recommendations and unique activities for a 16 year old?

Hey everyone! I’m bringing my nephew to NOLA in March to celebrate his 16th birthday. It will be his first time. I’ve been several times but I want to stay somewhere new this time. So far I’m torn between the Brakeman, Hotel Provincial, and Loft 523. We will be coming the weekend of Super Sunday, and have planned to go to that, so somewhere that is close to the area that is held in would be good. We will not have a car but don’t mind walking. If y’all know of some better suggestions than these hotels let me know. Also do the live music venues allow teenagers? I know most of them have bars so I would assume no, but I wanted to take him to a show while we are here. Any unique activities a teenager might enjoy?
