We really enjoyed our stay at the granny flat. It was exceptionally clean and had everything we needed for our stay.
The check-in process and the detailed instructions provided were excellent. And we certainly felt secure!
We particularly liked the fact that there was central heating (and air conditioning) to all the main rooms.
For us the location was excellent, being a quiet neighborhood with only a 5-10 minute walk to the train station which provided convenient access to everything the Sydney area has to offer. (The Sydney commuter train system is excellent!) The local Woolworths supermarket is right next to the train station, so super convenient to pop in for supplies on the way back to the flat.
