Kharl's place is exactly as described and in a secluded side street just off Kings Cross. It's a 3 minute walk to the T station and a 15/20 minute walk into the CBD/Circular Quay area.
Myself and my girlfriend stayed in the apartment for 4 full days over New Years Eve and it was perfect for that sort of short break where you're out and about a lot given the central location.
The apartment was clean and had all the amenities required. Kharl had also left bottles of water and shower products which was much appreciated!
The best thing about the Airbnb experience was Kharl's responsiveness. He promptly replied to all my messages within an hour or two and made check in/out very easy.
I would highly recommend Kharl's place. Thanks again!
