This one isn't necessarily quiet, but what about a recorder? It's easy for kids to learn, inexpensive and portable. I played the recorder as a kid and I really enjoyed it. In high school, I moved from playing the recorder to playing the clarinet. The recorder is a good starter instrument, in my opinion.
I also agree that it's good to let the child pick which instrument to learn. But if you're right next to neighbors or have thin walls, I'd also suggest a keyboard (or guitar) with headphones.

The wood is critical here because the holes in the soundboard are often tiny. When buying a mandolin, you should pay attention to the overtones and comfort because the first thing you should be worried about in a musical instrument is whether it is comfortable for you to play it; only if you meet this condition, you will achieve mastery.
