Potts Point is a great neighborhood, with lots of bars and really good restaurants. Plus, the apartment was only 10min walk away from the Cross Station, which was perfect to go to the other parts of Sydney.
Sarah was an excellent host by being helpful and responding quickly, whenever we had an issue.
I'd say that the only "negative" point would be the mattress, which it wasn't enough firm for us. Otherwise, everything was perfect : it's a functional, clean apartment. I strongly recommend it if you want to visit Sydney!
