Which duplex layout better blocks kid room noise for neighbors?

I'm moving and found two duplexes that I'm interested in. I'd be sharing one wall with neighbors in each. One duplex has a room adjacent by a hallway and the other duplex has stairs adjacent from the room. Because my kid is very hyperactive and has an indoor trampoline I'm trying to figure out which would be best.

Stairs
Hallway
Both
