Casper's place is exactly as per described. It is clean and cozy, big enough for me and my colleague. His place is close to The Central station, is a walking distance to the city and there is a bus near his place that will bring you to Bondi Beach.
Gabi greeted us when we arrived and offered to help us with our luggage. She was so welcoming!
I would suggest everyone to stay at his place. :)
