We did not have the opportunity to meet Nathaniel, as he was travelling, but we met James, his housemate. Communication prior our arrival was excellent! Although Nathaniel was abroad, he arranged everything for us and kept in touch. When we got to his place, it was a terrible surprise to see that it was FILTHY! (common places and room). Our room seemed as if it had never been cleaned, and the bedsheets didn't seem fresh either. In fact, we had to vacuum and refresh the room upon arrival. In the kitchen there were cockroaches (small ones), and the curtain in the shower was covered with mould; one could tell that maintenance was not the strength in this house. As those were our last days in Sydney and location was convenient, we decided to stay, though we cleaned the areas we needed in order to make our stay a bit more pleasant. Despite all this, our host, James, was really nice; he even gave us a lift to the train station the last day. If they made the effort to keep their place clean, this listing would be definitely a great one (good location, welcoming hosts, air con in the room); otherwise, it's not recommendable, unless you don't mind staying in a dirty place.
