If you search "aus99 map" in google you'll find the thread for a Sydney google maps of loads of rnts and brothels all over the Sydney, helpful to get a lead in an unfamiliar suburb. As for Rydalmere, yeah that row of shops across from Aldi (and next to a playground) are the only ones, haven't been to any of them. You'll have better luck down the road at West Ryde and Ryde itself, much more choice
