Not very good at writing these things, but I'll give it a shot.
The apartment was great for me. I was just one traveler (from the US) and it was perfect. As I like my space, it would be hard to imagine another person or two in the studio, but that's just me. It was very clean and close to anything you need. The transportation system in Sydney makes it so that it's easy to get anywhere without a car. I almost rented one. Don't do that. Parking is a pain there. I was a bit worried about having no AC, but I kept the windows open the whole time so I had a lovely breeze and the weather was actually quite lovely. Dare I say it felt BETTER than being in air conditioning all day. There is a mini-fridge and a stove/toaster oven combo. Some ppl complained about the stove taking too long to warm up, but it worked just fine for my purposes, which was warming up meals I had purchased from "About Life" grocery store which kind of like an Australian Whole Foods (for those of you from the US)... and just around the corner from the apartment (on Crown St). If you are used to buying organic/slightly higher quality foods and more natural options in body products, then that is the place to go. The only part I didn't like is dragging my luggage up and down 2 flights of stairs. I'm NOT a light traveler though, so take that comment as you will. Casper's mom was super friendly and even brought me a new iron super quick when there was a problem with the one there, and his aunt was kind enough to take me to the airport after check in to get my bags and help me up the stairs with them. With my calf being strained, that was SO much appreciated.
If you're on the fence, I say DO IT, unless they are having another heat wave (which I had just missed by a day). Then you may need some AC. ;)
