Vivien is a lovely and very friendly host and responded quickly when I had questions. What I liked about her place was the really comfy and big bed and the cute little kitchen, the check-in was uncomplicated and the surroundings were just as described, lots of restaurants and shops. Also, chocolates were waiting for us on the bed!
However, I booked several accomodations in Sydney for our vacation and to be fair I have to say that compared to other same-sized apartments in the same or even "better" parts of the city I think it's a little bit too expensive given the fact that it is indeed very, very small; I would not recommend it for more than one or two people. We both were surprised because the photos really didn't show how small the place actually was, so we had a little trouble storing all our luggage and had to climb over the suitcases whenever we wanted to take a step.
Also, compared to similar priced apartments which were a lot bigger I think the details could have been a little better: The bathroom and the corners of the room were not as clean as we'd liked it to be (found some long hairs and dust here and there), soap, spare towels and toilet paper were just lying on the bathroom floor, the bed was (though wonderfully clean and comfy) squeaking VERY loud at the tiniest move and when we booked the apartment there were no pictures of the bathroom yet. I know they have been added now, but it feels a little weird to shower with the sink and bathroom cabinet inside the shower. You have to clean everything before you can put on make-up or do your hair after showering.
All in all it's a nice place to stay if you need a little apartment to sleep in and explore the city from, but - as said before - compared to our other apartments which cost the same amount of money it could be a little cheaper.
One last thing I'd like to mention for travellers with small children or simply the will to go to bed early: We were staying for two nights and the neighbours upstairs (you can't enter that part of the house because there's a locked door in the hallway) were making a terrible noise in the evenings, there were clearly adults playing ball with their kids in the staircase for hours, literally screaming, squeaking and shouting all the time. When I asked them to be more quiet, none of the adults responded and they kept screaming for another few hours until about midnight. Of course this has absolutely nothing to do with Vivien but I wanted to mention it. Also, I don't know if those people were residents or travellers just like us.
