I enjoyed my stay in Haberfield. The studio is very nice and cosy and the location is good.
The internet connection is amazing fast, bed and linnen are excellent and the kitchen is complete. Even a dishwasher if you're a little bit lazy...
I found the road to the train station or the metro station too long because it goes up and down and is sometimes very steep. But the bus stop is really next door. It runs every 20 minutes and gets you to Ashfield or Strathfield station where you can catch the trains to nearly everywhere.
Anyway, with the Opal card, It's about the same price.
Do'nt forget to download the Opal App. Very handy.
