Lucas was friendly and helpful - as was his roommates and pet rabbit - but left me be when I wanted. The apartment is in a good location, about a five minute walk to a couple of bus stops that'll take you to the CBD and surrounding areas, with a gym and pool complex attached should you be into that sort of thing. The bed was comfortable and well stocked with blankets for the cold nights, though given the room's wall to the outside is all glass if there's a house party across the street (as there was on the Saturday I was there) you can hear it pretty clearly - not an issue most of the time however. The kitchen and bathroom are definitely lived in but clean enough, and the only other thing I'd be aware of: you've got visual privacy but not aural - the room is a partitioned area of the living room and there's an air gap at the top, so sound travels freely. Thankfully Lucas and co were quiet so this wasn't really a problem while I was there.
Overall it was very much a pleasant stay and a good budget option for Sydney.
