Atari was an excellent host: always available for contact, very warm and welcoming, and gave me great advice about the services and interesting places to visit in the area. And his apartment is outstanding: very light and roomy (especially with the many large windows and high ceilings), walking distance to the city and public transport, and being at the rear of the building, very quiet. It had a great open feel to it with views of some greenery and buildings on William Street.
When I return to Sydney, *this* is the place that I would like to stay. Highly recommended.
