Grant's place is wonderful! Exactly as pictured, very clean, and well situated. Grant thoughtfully made sure there was milk, eggs, tea, and coffee in the apartment when I got there and helped out with anything I needed to know about the area.
The place is right next to Sydney Uni and a 10 minute walk to UTS, so if you're looking to be close to the unis this is the place for you. It's not quite downtown, but you can get there on a short train ride, and the neighbourhood itself is lovely and quiet. If you're looking for a party, Newtown is just 1 stop away or a 15 min bike ride.
If it's not already obvious, the selling point to this place is the rooftop. During the summer it gets hot in the afternoon, but in the evening it's the perfect place to unwind with a view of the city. Also provides lots of light to the apartment itself. The kitchenette is great for making light meals and breakfast (I made omelettes and stir fries most days), but if you're looking to cook up a storm it'll be a little cramped.
Bottom line: if I were heading back to Sydney, I'd give Grant a call and stay here again. Definitely recommended!
