Aya's place was fantastic.
I'm from Sydney and was back visiting with my partner and 1.5 year old. We stayed for 10 days and the apartment was a perfect home base - beautifully decorated, free from clutter and with everything we needed. Nice touches like quality soap/ shampoo etc was appreciated, as was setting up a booster seat and crib. Location-wise I'd say it would be hard to beat, walkable to so many excellent coffee shops, cafes, restaurants and pubs, close to public transport to take you to the beach, city or other inner suburbs, walking distance to Newtown and Erskineville. The apartment is situated in a leafy complex on a quiet street where we never had trouble finding a parking spot.
As someone who knows the Sydney area very well I highly recommend Aya's place.
