Coturnix quail make great house pets! The females are quiet, have a pretty song, and produce eggs like crazy. They come in a variety of colors. My favorite are the whites, with the brown splotches. So pretty!
The males are kind of noisy for indoors, but they're still sweet and beautiful and can be very friendly.
If the cage is clean, they are no smellier than other birds (parakeets, etc.). And in a calm and comfortable environment they can be quite tame and calm. It's only in brooder situations that they're flighty and afraid.
Good luck!
P.S. When I say the males are noisy, they are still quieter than a parrot or similar. So it's definitely doable, just depends on your noise tolerance.
