I had a nice time in this charming apartment, which was conveniently located on a rather quiet street close to Kings Cross station. There were some nice places to eat nearby, and it's one train stop away from the city center (or a 30 min walk). Erika was very responsive and flexible. I wanted to stay an extra day, and that was no problem at all.
I was in Sydney for work and had get some work done while I was there. The apartment wasn't ideal for this purpose, since the chairs in the apartment were not so comfortable and wifi could be a bit patchy sometimes. However, there was a Joe and the Juice right around the corner, so it was easy to get my work done there. Also recommend the city library close to Martin's place.
