This is a self contained granny flat at the back of a house (but completely separate). Nice and comfy. Would be great for one, two, and there's a spacious couch for a third person.
Right near Addison Road Markets, The Henson pub, Illi Hill and Two Chaps cafes, Henson park/oval, Newtown/Enmore and Petersham. 25 minutes from the city on public transport. Please be aware that being in Sydney's inner west, you may see a cockroach.
