Like all of the others here have said - NO WAY!
My neighbors got 20 of these and they are LOUD. They're down to 3 and... still LOUD. All of the time, no matter what. Plus, their poop smells worse than chicken poop - think of something dead that was dug up from the bottom of the garbage dump. And it's all over my front step, car, and window sills, and patio furniture (guineas typically like to hang out of the neighbors instead of at the owner's). They peck at the paint on the car (oooh, shiny!) and they eat my tomatoes!!! I've learned to sometimes hate my neighbors... but then, if you're in New York and that's your point (to piss off your neighbors) then, yes, you should get guineas.
