If your neighbors wouldn't like roosters, they'll hate guineas. Mine did (they objected to the poop, not the noise) and it now means I have to keep my guineas penned 24/7, although I do take them out for "walks" around the property as often as I can. It's not much, but it's better than nothing.
Guineas don't suit everyone, and generally they aren't good with close neighbors unless you can enlist their support from the beginning. If they aren't "guinea people" then they will make life miserable for you.
Do you have chickens? Chicken hens are generally acceptable to just about everyone - especially when they get some free fresh eggs! (Although my neighbors wouldn't get a fresh egg outta my flock now! LOL)
